Fetty Wap just got hit with a battery charge stemming from his melee with security at a Vegas casino ... and surveillance footage shows the rapper landing some haymakers!!!

According to legal docs obtained by TMZ ... Fetty is charged with one count of misdemeanor battery for striking the security guard in the head.

Ya gotta see the video from outside the Mirage Hotel and Casino where last month's fight went down ... you see Fetty connect with two punches as guards swarm and try to bring him down during a huge scuffle.

We broke the story ... Fetty Wap was busted in September after a fight broke out in the casino parking lot, and Mirage security made a citizen's arrest until Las Vegas Metro PD showed up and took him into custody.

Kanye West has gone international with his Sunday Service ... this time the destination was Jamaica.

Kanye barreled into Kingston Friday for a concert in Emancipation Park, to the delight of a huge crowd that crammed into the space for the 2-hour service.

No sign of Kim and the kids ... they could have made the trip, but they were nowhere in sight.

Kanye did bring along a choir of at least 120 people. He opened the service with the gospel song, "Prince of Peace," and also performed Damian Marley's "Welcome to Jamrock." He closed the show with "Jesus Walks."

The concert was made even better by weather conditions ... it was a cool, breezy night.  Some of the people in the crowd were so overcome with emotion they were sobbing.

Kanye and company were all wearing City of Kingston shirts. He launched Jamaica themed merchandise on his online shop.

Some people on social media, however, blasted Ye for profiting off government logos without paying royalties.

DaBaby is helping a homeless mother climb out of poverty after shouting out her hat business on social media ... because her products are now flying off the rack.

Since DaBaby pimped Amanda Rose's beanie biz on Instagram, following a chance meeting at his pop-up shop in Atlanta, the 23-year-old mom tells us she's received over 4,000 orders for her handmade hats.

DaBaby's clout is pretty enormous ... Amanda tells us before getting the rapper's endorsement, she was barely making ends meet with 3 to 4 orders per month.

Amanda, who's been living out of a 1999 Nissan Maxima with her son Nick, waited outside DaBaby's pop up for 3 hours hoping to meet him and sell him a hat. When she finally got inside, DaBaby delivered way more than just a single order.

It's pretty crazy ... DaBaby gave her $1,000 on the spot and filmed a quick hit for her hat biz, Lovely Stitching. With thousands of orders flowing in within a matter of hours, Amanda rushed to create a website, and she tells us she's saving up to rent an apartment.

Mike Posner's putting 6 months worth of wear and tear on his feet behind him with a big dip in the Pacific, and ya can't say he didn't earn it ... after WALKING damn near 3,000 miles!!!

The EDM star completed the trek -- from New Jersey to California -- in 6 months, and by his count, he covered 2,851 miles over that period. Mike celebrated when he reached the sand on Venice Beach by jumping in the ocean.

Not only was it not easy ... it could've killed him. You'll recall ... Mike was bitten by a baby rattlesnake back in August as he made his way across Colorado. After a few days in a hospital, he got back on the horse ... or his feet, albeit with the help of a walker.

Mike had been logging about 24 miles per day, but the snakebite slowed his pace for a while.

Still, he trekked on to complete the journey. He told us way back in April when he started that the deaths of his father and Avicii inspired him to make the trip ... and he hoped to inspire others to achieve their goals.

His personal goal was to reach Cali by October, so he nailed that. If anyone deserves a massage on the beach today ... it's you, Mike!!!

Kanye West's crusade to corner the market for his Sunday Service gear just got shot down by the trademark gods ... of the U.S., anyway.

Ye applied for exclusive ownership of the mark, "Sunday Service," to slap it on clothing, dresses, footwear, headwear, jackets, loungewear, scarves, shirts, socks and tops. But, the U.S. Patent and Trademark Office shut him down because, basically ... someone's already working that corner!!!

According to the docs, obtained by TMZ, someone else already registered the name -- and therefore Kanye using it would likely cause confusion in the marketplace.

We broke the story ... Kanye applied for the trademark in July. He'd started selling gear even before that, on Easter Sunday, to coincide with his performance at Coachella. He was hawking hoodies for $165 and $225 a pop and socks for $50.

Since then, his Sunday Service events have become a weekly attraction all over the country -- from Wyoming to Queens, NY -- attracting big crowds and celebs.

Fugees rapper Pras says when it comes to singing the n-word ... Gina Rodriguez has to earn a pass. Question is ... has she?

Pras hopped on "TMZ Live" Friday and let it be known that only certain Latin people who have contributed to the culture and those deeply embedded in the black community are given an honorary pass to say the word while singing a song.

As far as Gina's concerned ... Pras says he knows she's Latina but doesn't know her background well enough to speak on whether to issue her an honorary pass or not.

As we reported ... Gina got a lot of heat earlier this week for saying "n***a" while singing Lauryn Hill's verse on the Fugees' 1996 hit, "Ready or Not."

"Love & Hip Hop Miami" star Amara La Negra and Boyz II Men singer Shawn Stockman say Gina's earned the green light ... but seems the debate rages on.

Lady Gaga came way too close to the edge of glory when she invited a fan onstage and leapt into his arms ... because he was not ready for the spotlight.

Gaga was in the middle of a performance for her Las Vegas residency show, 'Enigma,' Thursday night at Park MGM when she brought the fan, Jack, up to join her.

Jack looked like he didn't want to let go when Gaga gave him a hug, so she obliged and decided to jump up and wrap her legs around his waist ... and that turned out to be a very bad choice.

After a few little hops and twists, everyone's laughs and cheers turned to gasps as Jack took a misstep off the right side of the elevated stage and went tumbling off ... still holding on to the star of the show.

The 2 crashed hard, and it looked like Jack came down on top of Gaga. Here's another angle.

The good news ... everyone seemed to be uninjured after the nasty spill, and Gaga announced to the crowd that everything was okay. She added ... "The only thing that’s not okay is we need some stairs for the damn stage so I can get back up."

The singer also consoled Jack, who was apparently in tears after the fall, and invited him back up to sit with her as she played piano and performed "Million Reasons."

She told him ... "Could you promise me something? Could you forgive yourself right now for what just happened?" and added, "I think that’s amazing. We f****g love each other so much we fell off the damn stage."

What a pro. Her post-concert ice bath and hot bath was extra necessary after this one.

Elton John and "Rocketman" star Taron Egerton performed Thursday night in L.A. ... but lots of fans were super pissed they sang a grand total of 2 songs.

Fact is ... it was always billed as the Hollywood Symphony Orchestra playing the soundtrack to the movie "Rocketman" at the Greek Theatre. But, the billboard for the concert clearly says it features Elton and Taron ... so lots of fans felt shortchanged.

After the Symphony did its thing, Elton and Taron came out and performed "I'm Gonna Love Me Again," and "Don't Let the Sun Go Down on Me" ... but that was it.

Billie Eilish's big brother says he looks up to his little sis for inspiration now that he's taking his own music career on the road ... even though he's already the brains behind her brand.

Finneas O'Connell talked to us Wednesday at LAX, just hours after his first big solo show -- sans Billie -- out in SF ... where it looks like he killed it all by himself.

The guy's a first-rate musician, and if you didn't know ... he actually cowrote and produced most (if not all) of Billie's tracks on her album, "When We Fall Asleep, Where Do We Go?"

Considering he has usually accompanied Billie onstage when he's performed until now, we were curious how he handled the audience, and if he took any cues from Billie herself ... seeing how she's got incredible stage presence and knows how to rock a crowd.

Turns out ... Finneas actually took diligent notes on how Billie handles herself during a performance, and it sounds like he applied some of those techniques for his own gig.

Now, for the juicy question ... does he, ya know, resent folks who might show up to his shows just because they're Billie fans? Check it out ... Finneas is a class act, telling us he'll take the support either way, but he DOES appreciate one type of fan in particular.

Shawn Stockman is giving Gina Rodriguez a pass for singing the n-word ... he says it's totally fine because her parents are Puerto Rican, and Latinos are black.

We got the Boyz II Men singer Wednesday at LAX and asked him to weigh-in on the backlash Gina's getting after saying "n***a" while singing along to the Fugees on social media.

Shawn says he's not offended by Gina's use of the word, and he goes one step further ... saying people of Puerto Rican, Cuban, Dominican and Mexican descent can say "n***a" because they're all different shades of black.

Gina quickly apologized after her social media post went viral, saying sorry for offending anyone and explaining her connection to Lauryn Hill and the Fugees. But, Shawn thinks Gina has absolutely nothing to apologize for.

There's no holding back Travis Scott when he's in the mood to go clubbin' ... not even a dislocated knee.

The "SICKO MODE" rapper hit some of the most poppin' clubs in WeHo Tuesday night ... and we got him at almost every stop. Travis made his first stop at The Nice Guy -- where we saw him walking with a severe limp ... hopping into his waiting Bentley.

We also got someone on his team loading Travis' crutches into a separate car. Travis and his crew later headed to Delilah before showing up at Bootsy Bellows. On his way out, Travis needed help from a handler.

A$AP Rocky says he's a sex addict ... and has been since junior high school. Those are his exact words.

The rapper opened up to NYC host and Power 105.1 DJ Angie Martinez on her show, "Untold Stories of Hip Hop," and revealed the bombshell. It's no secret A$AP's been obsessed with orgies for a long time. He talks about it a lot, but this is the first time he's gone so far to say he's addicted.

In this preview clip, Rocky says he was always a horny kid. Angie presses him, pointing out there's a difference between being horny and being a sex addict. A$AP doubled down with his sex addiction diagnosis -- although it's unclear if that info came from a trained professional. Therapist, that is.

Cardi B isn't kidding when she raps about liking diamonds, stunting, shining and million dollar deals -- enter Offset with her whopping 20-carat birthday gift, which IS worth over SEVEN FIGURES!!!

The Migos rapper reached out to Pristine Jewelers in NYC about 9 months ago -- and owner  Avi Davidov tells us Offset made it clear he was looking to score something incredibly special for Cardi's 27th birthday.

We're told Offset already had an idea in his mind -- a heart-shaped diamond surrounded by smaller hearts. The center stone is a brilliant 20 carats. The diamond ring's been dubbed the Titanic Diamond for its size and similarity to the Heart of the Ocean rock from the movie. It's complemented by a band of smaller diamonds that total 25 carats.

We're told Avi literally hand-delivered the rings on a silver platter last weekend. As we reported ... Cardi was damn near knocked off her heels when she saw the stunning rings.

Justin Bieber's personal Instagram may be more effective than the Multiple Listing Service in moving real estate ... because his one post declaring he's in the market to sell his house has generated tons of interest ... including from at least one billionaire.

Bieber -- who boasts an insane 120 million followers on IG -- casually mentioned last week he's looking to sell his Beverly Hills home ... "I'll sell it with all the furniture. MAKE AN OFFER."

Sources with direct knowledge tell TMZ ... Justin's been contacted by at least 5 prospective buyers ... either directly or through their realtors. We're told one of the prospective buyers is a billionaire from a very famous family.

New York City's biggest hip-hop radio station says Tekashi 6ix9ine will get no spins once he releases new music ... unless the snitching rapper's music forces their hand.

An executive from HOT 97 FM tells TMZ ... when Tekashi is released from prison and drops new music, the radio station will NOT jump to debut any of the records, and they don't anticipate playing any of 6ix9ine's music at all.

Fact is, the exec tells us HOT 97 has NEVER been a huge Tekashi69 supporter, and him ratting on former gang members is digging an even bigger hole for himself as far as the radio station is concerned.

We broke the story ... one record label is making a multi-million dollar investment in Tekashi, banking on him getting out of prison sooner than later and surviving all his snitching.

The big boss man behind the City Girls says JT is so focused on cranking out new hits ... she went straight to a studio even before hugging her mom when she got outta prison.

We got Pierre Thomas -- Quality Control Music cofounder -- at LAX and he told our guy he's expecting big things from the City Girls now that JT is no longer behind bars, and they're hard at work to prove him right.

Pee says JT and Yung Miami are busy working on their new album, and spoiler alert -- he tells us it's dropping sooner than you'd expect!

TMZ broke the story ... JT is living in a halfway house now to complete her prison sentence, and she's allowed to leave during the day to record music.
