Justin and Hailey Bieber are having a hard time finding the perfect day to celebrate their union, because we've learned the couple is postponing their second wedding ceremony ... AGAIN.

Sources familiar with the planning tell us some of the 300 guests who received JB and HB's "save the date" were notified Tuesday that their second round of nuptials is being rescheduled ... for the third time.

We're told the Biebers got some regrets back from certain loved ones who couldn't make it to Los Angeles for the weekend of Justin's birthday at the beginning of March, as was originally planned, so it's back to the drawing board. 

We're told Justin and Hailey initially panicked and started to scramble for another date, but then it dawned on them -- THEY'RE ALREADY MARRIED, so there's no rush.  

Our sources say the wedding will not be anytime soon ... they want to properly plan it this time with plenty of warning for guests. We're told they're now thinking they may want to do a destination wedding, knowing that would pare down the guest list considerably.

We know some of the guests Justin and Hailey had invited include Kylie Jenner and Travis Scott, Chris Brown, Drake and Odell Beckham Jr. 

4th time's a charm?

The MAGA hat-wearing student who faced off with a Native American Vietnam vet says his smirk seen 'round the world wasn't out of smugness ... just peaceful defiance.

Covington Catholic High School junior Nick Sandmann appeared on "Today" Wednesday with Savannah Guthrie, who grilled him on a number of topics -- most importantly ... why didn't he just walk away, and what was up with that smirk on his face?

Sandmann says, in hindsight, he wishes he would've just walked when Nathan Phillips came up to him drumming. That said, he explains that, in the moment, he felt leaving or making any sudden movement would've escalated the situation.

On that smirk ... Sandmann says it was just him smiling with the message of, "[T]hat is the best you're going to get out of me, you won't get any further reaction of aggression and I'm going to stand here as long as you want to hit that drum in my face."

Sandmann further explained people who have come to judge him based on one expression they saw have jumped to harsh conclusions based on mere assumptions.

The full interview can be watched on the "Today" website.

Alec Baldwin just got a great result in his criminal assault and harassment case, after prosecutors realized the surveillance video created huge problems for them.

Baldwin appeared in an NYC courtroom Tuesday and prosecutors revealed they were willing to not only lower the charge to harassment in the 2nd degree, but they also cut a deal in which Baldwin would take a few anger management courses and the whole thing would just go away.

The case involved a parking dispute back in November between Baldwin and another man outside the actor's NYC apartment. Baldwin felt the guy underhandedly swept in and took his spot. The guy claimed Alec punched him in the jaw and filed a police report.

TMZ broke the story that the surveillance video did not show Baldwin punch the guy. Rather, it showed the 2 men shoving each other, which is consistent with mutual combat.

Prosecutors told the judge after reviewing the surveillance video and speaking with witnesses, a lower charge was appropriate.  

Bottom line ... this is a win for Baldwin. Although he pled guilty to the lower charge, the case will be closed as long as he completes the courses. His next court date is March 27. 

Priyanka Chopra and Sophie Turner were just a couple of future sister-in-laws about town this week ... and apparently, Tuesdays are just for the girls. 

PC and ST hit up Craig's in WeHo together, where they were swarmed by paps, all of whom were eager to snap a shot and fire off a question.

Gotta say, we haven't seen a reaction like this to a celeb pairing out in Hollywood in quite a while. It just goes to show how much star power these two have racked up since their engagements and wedding(s) thus far to Nick and Joe Jonas over the past year or so.

Speaking of nuptials ... Joe and Sophie are reportedly set to wed sometime this year, as 'Save the Date' boxes have already been sent out to potential guests. Nick and Priyanka already got that part done -- they did it to death, in fact, with 3 ceremonies.

If Sophie and Priyanka's family power outing is any indication of what's to come ... we say bring on another one sooner rather than later. 

Chris Brown is going on the offensive after his arrest for allegedly raping a woman in Paris, because he's going to sue her for defamation.

Chris' Parisian lawyer, Raphael Chiche, says, "Chris Brown is free. No lawsuits were filed against him. He vigorously challenges the charges against him. A complaint for slanderous denunciation will be filed tomorrow with the public prosecutor of Paris."

As we reported, Chris claims he was set up by the 24-year-old model, who claimed Chris took her to his hotel in Paris and violently raped her. Chris called BS, saying he was never alone with the women.  We're told he insists he was playing music off his iPhone in the living room of the suite with 20 people around him the entire time.

Brown was released from police custody Tuesday, but prosecutors say the investigation is still ongoing. A source in the judicial system of Paris tells TMZ the fact Brown was released with no conditions and free to leave the country is a sign authorities have problems with the case. 

Vinny Guadagnino made his pitch that fellow "Jersey Shore" star Mike 'The Situation' Sorrentino could do way more good if he weren't behind bars ... and he made the pitch to Kim Kardashian.

We got Vinny Tuesday at LAX, and he said his buddy is doing fine behind bars. He was worried, but he's been assured by Mike's wife, Lauren, he's doing great.

After some talk about getting jacked in prison, Vinny makes his pitch to Kim, who's batting 3-0 in her effort to free certain inmates. 

We're guessing Mike shouldn't hold his breath. 

Meek Mill and The Game sure know how to bury the hatchet in a big way -- throw down the shovel and hit the studio, which is exactly what they've done ... TMZ has learned.

Sources close both MCs tell us that they recently got together to collaborate on new music -- this is after Game officially announced their two-year feud was over.

We're told Meek flew out to L.A. last week to record a new song for Game's forthcoming album. Our sources say the get-together proved to be super productive ... not just musically, but in repairing their once-fractured relationship. We're hearing Game and Meek chopped it up and even had a good laugh over the 2016 beef ... which seemed nasty at the time.

If you'll recall ... Game thought Meek had ratted him out to Sean Kingston after Sean was robbed one night in the summer of '16 at an L.A. nightclub they'd all attended. Game says Sean told him Meek claimed Game was behind the robbery ... which Meek denied.

It was basically a case of he said, he said and he said ... and in the midst of all of it, some harsh diss tracks were exchanged between Game and Meek.

That's all water under the bridge now though. Look out for their new collab to drop in the near future.

President Trump's ban on transgender people serving in the military doesn't make any sense to retired Navy SEAL Kristin Beck ... because she says trans soldiers are just as effective killing machines as their counterparts.

Kristin, a transgender woman and former SEAL Team Six member, tells TMZ ... the reasoning behind the ban -- trans service members aren't as lethal -- doesn't hold water, because she knows lots of openly trans people in the military who are great at their jobs. 

Trump's ban barring most trans people from serving in the military was revived Tuesday, after a 5 to 4 vote by the SCOTUS ... and Kristin is pissed! 

Watch ... Kristin explains why trans service members are just as effective, and she says it's an awful idea to turn away people who are willing to serve our country.

Lil Pump's thirsty, and now he's got sodas from all around the world to quench his thirst ... thanks to his very own, one-of-a-kind vending machine.

The "Butterfly Doors" rapper's been showing off his new customized soda dispenser from Exotic Pop, which is a prototype that comes with an Apple TV installed ... so he can rock out while he pops out.

Charleston Wilson, the owner of the Houston-based beverage company, tells TMZ ... Pump started hitting up their location outside of L.A. a while back for rare flavors, but inquired about getting his own machine a couple months ago.

Wilson says because LP's been such a great brand ambassador for Exotic Pop, the company decided to gift him the customized pop machine this week. We're told it contains sodas from Japan, Poland, Canada and more ... and costs around $10,000.

Lil Pump's also in talks about getting his own soda too.

BTW, he's not the only rapper affiliated with the brand ... Drake, Migos, Lil Yachty and Soulja Boy are also fans and customers.

Before this fancy fella was a professional skateboarder, he was just another little lad dressed to impress in La Palma, California. Can you guess who he is?
