Justin Bieber has a lot of reasons to smile with his wedding ceremony fast approaching, and now he's got one more ... in the form of some new pearly whites purps!!!

Sources tell us the singer got this brand new grill from L.A.-based jeweler Gold Teeth God. It's a purty purple color -- lavender actually, as we're told -- and covered in imported 5-carat diamonds from Israel.

There's also this ... our sources say the bling can fetch up to $25k on the market, although it's unclear if that's what the Biebs actually paid for it.

Still though ... that's a whole lotta fancy in his mouth.

The Game is calling out Tekashi69 ... calling the kid's snitching something a fake ass gangster -- and not a real Blood -- would ever do.

We got Game Tuesday in downtown L.A. at MedMen ... and the rapper unloaded on Tekashi for singing like a bird on the witness stand. Game confesses he actually feels sad for the kid ... because he got himself into a mess after claiming to be something he's really not.

Plain and simple ... Game says Tekashi shoulda kept his mouth shut.

Probably didn't take 'em more than one phone call, but Justin and Hailey Bieber locked down their first choice for a wedding singer -- and Daniel Caesar will be doing the honors.

Sources with direct knowledge of this weekend's ceremony tell us ... the R&B star will be on the mic when Mr. and Mrs. Bieber celebrate their union in South Carolina with family and friends.

Justin's keeping it Canadian by enlisting Daniel, but we're told it's more than national pride -- Daniel is Hailey AND Justin's fave singer right now. Daniel's debut album, "Freudian," went gold and spawned a #1 hit on the R&B charts ... "Best Part."

It's a good bet he'll be singing that one when the nuptials go down on the Carolina coastline in Palmetto Bluff. As we first reported, the couple finally settled on Sept. 30 for the big ceremony they've been trying to pull off.

Aaron Carter is no longer a gun owner, telling us he sold all of his firearms ... and he says he's also getting treatment, but not because that's what his family wants.

We got Aaron running errands near his home in Lancaster, CA and he told us he's done with his family after getting hit with restraining orders from brother Nick and sister Angel ... and he's also done with his guns.

Aaron tells us he's officially sold his firearms -- remember, he had at least two assault rifles, a pistol and a shotgun -- and the singer shows us the paperwork as proof. Dude means business.

Young Dolph found himself in a pair of cuffs after police thought they smelled weed when they pulled him over in Atlanta ... but there were no drugs in the car, and Dolph walked free.

Video of the incident -- obtained by TMZ -- shows the rapper standing outside his Mercedes-Benz G Wagon being detained by police officers, while his pals sit on the curb in handcuffs.

Law enforcement sources tell TMZ ... Young Dolph's car was pulled over Tuesday afternoon because he was not wearing a seat belt while driving, and cops thought they smelled some chronic when they went to the window. So, they pulled everyone out of the whip and cuffed 'em.

Our sources say police searched the car, but couldn't find any ganja.

Miley Cyrus' iHeartRadio set in Las Vegas nearly took a dark turn due to a man cops say is obsessed with knocking her up -- and it was only her eagle-eyed bodyguards who prevented disaster.

Law enforcement sources tell TMZ ... cops were called to the T-Mobile Arena Saturday night after Miley's security team noticed 42-year-old David Rumsey in the audience. We're told Rumsey was on their watch list because he'd allegedly made previous threats against her.

Our sources say Rumsey told Miley's team, "It's my life's mission to impregnate Miley." We're told the guy also claimed he was going to raise Michael Jackson and Prince from the dead so they could party with him and Miley.

After being detained by Miley's security team, Rumsey was arrested and booked into the Clark County Jail on a felony charge of making threats. He is still currently in custody.

The guy's Twitter feed is frighteningly bizarre. In tweets the week before the concert he tells Miley he's sorry for hurting her and blames Donald Trump. Then he insinuates that after they meet in Vegas they'll be able to party with MJ, Prince and Tupac.

Sources tell us those twisted tweets are why Miley's team had distributed Rumsey's photo to staff inside the venue and instructed them to be on the lookout during her performance.

Mission accomplished for Team Miley.

Young Dro's gonna have to spend time behind bars for smashing banana pudding in his GF's face ... but it ain't all bad news for the rapper, far from it.

According to legal docs ... Young Dro pled guilty last week to 1 count of battery/family violence. He was immediately sentenced to 12 months behind bars, but was only ordered to serve 70 days.

And, it gets even better -- Dro got credit for 20 days already served. Plus, we talked to a Fulton County Court official who tells us he'll get an extra day of credit for each day served on good behavior.

The official says, do the math, and the rapper could get out as early as October 5.

He'll remain on probation for the balance of the 12-month sentence. As part of his plea ... Dro's gonna have to submit to a drug/alcohol evaluation within 30 days of his release from jail. He's also been ordered to undergo domestic violence counseling, and cannot booze or take drugs while on probation.

He'll also have to take random drug tests and forfeit all weapons.

TMZ broke the story ... the rapper was busted back in July after allegedly punching his GF so hard it left her bruised. Young Dro's also accused of smashing a plate of banana pudding in her face before grabbing a kitchen knife and going to town on the living room furniture.

Billie Eilish says it's news to her that people plan to impersonate her for Halloween, but now that she knows ... here's a tip on the best costume from the woman herself.

We ran into the pop sensation Monday at LAX and asked her what look SHE would recommend to all the wannabe BEs out there. She acknowledged there are many, MANY options for her fans to replicate.

Aside from her hit music ... Billie's become a bit of a fashion icon over the past year. She's debuted a TON of unique outfits in each of her music videos. Even in this clip, she's got her own steez going strong.

One thing is clear ... Billie's having just as tough a time as her fans probably are in choosing a favorite outfit of hers. Her bottom line seems to be ... power to the people!

She did let us in on her personal Halloween plans, and she knows for sure what she will NOT be dressing up as come Oct. 31.

For those itching to make a splash with their own Billie Eilish costumes this year, you might not need to look further than her video for "all the good girls go to hell." Remember, she got (fake) tarred and feathered for that shoot ... and it's a perfectly hellish look for the occasion.

Just sayin' ...

A camera crashing down into the Life is Beautiful music festival left 3 women injured -- and 2 of them needing immediate medical treatment.

The scary accident happened Saturday night at the Las Vegas festival ... a huge camera fell about 35 feet, landing on top of the victims. We're told the camera was fastened to a cable, but slipped off ... sending the camera and pieces of its rigging plummeting into the crowd.

We're told the whole apparatus weighs about 20 pounds!

All 3 women were treated on scene, but 2 of them needed more assistance and had to be rushed to a hospital. We're told one woman was treated for a head injury, and the other for a leg injury. They've both been released.

The group Of Monsters and Men was performing on the main stage when the camera free fell ... creating, as you can see, a very bloody scene.

A rep for the festival tells us, "The safety and security of our guests, partners, artists and employees is our first priority. Our thoughts and well wishes are with those affected by the incident." They also say there is an ongoing investigation and they are working to identify the cause of the incident.

It's the second straight year equipment has injured people at Life is Beautiful.

The Postmates delivery driver Lizzo publicly accused of food theft says her days since then have been the worst of her life -- she's humiliated, terrified and worst of all ... it's a bum rap.

The driver, Tiffany W., tells TMZ ... her world was turned upside down when the "Truth Hurts" singer excoriated her on Twitter -- to her near-million followers -- saying, "this girl Tiffany W. stole my food she lucky I don't fight no more." Lizzo also included a screenshot of her profile photo.

This has scared the crap out of her. She's afraid to leave her home and even go to work, for fear someone might harm her or even worse.

As for the delivery incident ... we're told Lizzo's order was supposed to go to a Boston hotel, but there was no room number listed and no one answered the phone linked to the account.

We're told Tiffany went the extra mile and hit up the hotel concierge. She says she went into the lobby and continued to try to contact the customer and heard nothing back. Tiffany ended up waiting for a total of 10 minutes and finally left.

As for the food ... it was seafood, which Tiffany doesn't even eat.

A Postmates spokesperson tells us ... "As soon as Lizzo reached out, we looked into the matter and quickly resolved the issue. We apologize to Lizzo for any inconvenience." However, we're told the company determined Tiffany waited at least the required 5 minutes and wasn't able to reach the customer, so she moved on like she's supposed to do.

Lizzo's since deleted her original tweet putting Tiffany on blast and issued an apology ... but it seems like it might be too little, too late.

Kanye West's Wyoming Sunday Service appeared to go off without a hitch -- and it was definitely the place to be based on the sheer number of heads ... who came as they were.

The highly-publicized event started bright and early Sunday morning, with massive lines forming outside the Buffalo Bill Center of the West ... which is serving as host for Ye's latest gathering. According to eyes on the crowd, the estimated count was well over 700 people who'd come out -- well over the max capacity of BBCW's Powwow Garden.

Just to give you a sense of how many folks flocked in to catch Ye this weekend, check out this photo ... an absolutely packed house. Might as well have been a music fest.

Looks like Kanye and co. made due though, as early footage of the worship sesh showed everyone standing around the 80-man (and woman) choir, with Ye himself in among the group as well. He's the one with the yellow hoodie on down below.

As far as what was sung ... NIRVANA COVERS!!!! (but the Kanye hymn versions, of course). The choir sang their own renditions of "Smells Like Teen Spirit," "Come As You Are" and other Nirvana hits. There were some traditional prayers in the mix here too.

Eyewitnesses tell us Kanye did not perform this time around -- it's hit or miss with that, he's taken the stage at some stops lately, and other times he lays low and directs from the side.

According to what appears to be a setlist that was passed around, Kanye and the choir ended up running through 14 songs which included Ye's own "Ultralight Beam." There was also some nifty Wyoming Sunday Service gear for sale as well.

As we reported ... this week's Service was no secret. The Buffalo Bill Center made it clear that Kanye would be there and seemed to invite as many people as they could fit for free. As far as we can tell ... the homecoming was a complete success.

Kanye West wants his presence in Wyoming to be known far and wide -- it looks like he's hosting a mega Sunday Service this week, inviting all the townsfolk and their mom.

Ye's forthcoming Service is taking place at the Powwow Garden of the Buffalo Bill Center of the West in Cody, Wyoming -- where Kanye now owns a massive waterfront property, aptly named Monster Lake Ranch. Per local reports, the sign now reads "West Lake."

We already know he and Kim have made themselves at home -- getting acquainted with the local wildlife, to the chagrin of the Wyoming Game & Fish Dept. Now, it looks like Kanye wants to properly introduce the Wests to the community, 'cause his Sunday Service is being heavily advertised on a massive digital billboard, as well as on social media.

According to the venue's Facebook post about it, he's bringing out his "80-person choral group" for the performance -- so yeah, Kanye and co. are pulling out all the stops.

Preparations are currently underway for the free and public event, and it looks like they're expecting quite a turnout. Photos obtained by TMZ show a bunch of tents being set up Saturday ahead of Ye's Sunday Service, with catering and special event trucks in tow.

The Powwow Garden has a capacity of about 700 people -- 200 seated or 700 standing according to the Center's website -- but it's unclear how many people will actually show up. FYI, there are less than 10,000 people total living in Cody itself.

It's an interesting move on Kanye's part, as many of his Sunday Services of late have been relatively low-key -- not including the Chicago stop, of course. This appears to be the exact opposite of that -- pretty much a come one, come all approach.

DaBaby seems to have handled his own business for once instead of resorting to goons -- 'cause he appears to have thrown a punch at a handsy fan.

The North Carolina rapper -- who's been blowing up these past few months -- was performing Friday night as a headliner at the Prime Festival in Lansing, MI ... where at one point in the show, he seemed to hurl his fist (sloppily) at a guy in the front row.

DB probably had good reason to swat at him though ... looks like the dude got his paws on his chain, and might've even been trying to tug on it and snatch it away.

In video of the altercation, obtained by TMZ, DaBaby is below the stage level and face-to-face with the crowd, where only a barricade separates them. We're told DB was doing his thing, when someone close by reached up and made contact with his jewelry.

Well, DaBaby noticed and paused to throw a punch -- although, it's unclear if it landed properly or even made contact with the guy. After that, eyewitnesses tell us DaBaby hopped back onstage and finished out his 30-minute set ... immediately leaving the stage.

We're told nobody called cops and no one appeared to be injured -- so no harm, no foul really. That's good, considering DB has a bit of a track record being around beatdowns, allegedly at the hands of his entourage with him looking on.

While he did take credit for a beating at a mall once, after a dude relentlessly heckled him, it was not clear at the time if he'd handled the fella himself or not. Fast-forward to early August, when another fan got a thrashing ... and DB had his hands clean there too.

Now, it appears DaBaby took a swing on his own -- in clear view, without any convenient edits. Whether it's him or the homies, it's clear ... DB WILL come at ya. Take note, y'all.

This whole Area 51 thing kinda fizzled, but at least unseen aliens could enjoy a small, freaky dance party.

DJ/producer Paul Oakenfold performed at a festival called Storm Area 51 Basecamp. Thing is ... it wasn't anywhere near Area 51 Alien Center. Event organizers bailed on that idea and brought a free music festival to Vegas.

The dance party was a separate, 2-day event held at the Alien Research Center ... a souvenir shop 100 miles out of Vegas. Before the dance party, there was a screening of the movie, "Bob Lazar: Area 51 & Flying Saucers."

The original plan was for millions of people to storm Area 51 to "see them aliens." Millions didn't show up ... not even close -- more like a light sprinkle.

Britney Spears looked like she wanted to be anywhere else after she arrived with her boyfriend to the Daytime Beauty Awards, so after a few photos ... she was outtie.

Britney and Sam Asghari showed up to the awards show Friday looking stylish as they got out of their SUV, but as they walked up to take pics it appeared Brit immediately grew uncomfortable.

After a few seconds of cameras clicking and flashing, Spears said to her publicist ... "I just want to go."

She stuck around for a few more shots and forced smiles, but seemed to be urging Sam to keep moving ... until she finally had enough and said she was leaving.

Asghari -- who's being honored for Outstanding Achievement in Fitness -- had to reverse his course and walk her back to their SUV, where she got in and left.

Of course, this comes in the midst of a family showdown in court over Britney's conservatorship. As we told you ... a "fireworks show" was expected this week, but as of now things are still up in air.

Looks like Britney's feeling the effects.

Jennifer Lopez is here with a flashback Friday for the ages ... bringing back THAT dress -- y'know the one from the 2000 Grammys, and this time it stole the show at Milan Fashion Week.

J Lo hit the runway at Versace's Spring 2020 show Friday in a recreated version of her iconic Versace grown from nearly 2 decades ago, resurrecting one of the most memorable fashion statements in history.

Jenny rocked the throwback look with Donatella Versace walking her down the runway ... and the crowd went absolutely bonkers. Excuse us while we pick our jaws up off the floor.

Easy to see why J Lo got a standing O in Milan ... she's every bit as stunning in the plunging green dress as she was back in the day, showing off her flawless figure and leaving little to the imagination.
