Exclusive Details

Floyd Mayweather put cake to camera this weekend ... to show off a custom dessert at a belated Pacquiao victory party ... a dessert that's worth $15,000!!!!

It all went down at LIV nightclub in Miami -- where Mayweather was partying with a bunch of people from his TMT crew -- including DJ Jay Bling, Ricki Brazil and P-Reala.

At one point, Mayweather was presented with a 90-pound custom cake from Divine Delicacies
(coordinated by his friend Ms. Bling) ... a lemon rum cake that contained more than 10,000 Swarovski crystals!!!!

But get this ... we're told Floyd LOVED the look of the cake so much, he didn't want anybody to eat it until the party was over. At one point Floyd said, "I'm serious about nobody cutting my cake!"

We're told everyone obliged ... but when Floyd finally gave people the green light, only a few select people were given permission to dig in -- and didn't come close to finishing the whole thing.

Two Boston tow truck operators didn't want to go down as the guys who hauled off Rob Gronkowski's party bus, so they let him off the hook ... and the Gronk couldn't have been happier.

Matthew from Todisco Towing tells TMZ Sports he was called to Howl at the Moon in Boston early Sunday morning to haul off a bus that was parked illegally in a private lot.

Despite the bus being adorned with a Body Armor logo (which Rob endorses) and his #87 ... Matthew claims he had no idea he was about to tow Gronk's ride.

Once the bus was up on the truck and ready to go, Matthew says several patrons began asking him, "Don't you know whose bus that is?"

Then, someone from Rob's entourage came out and promised to move it ... and Matthew decided, "I didn’t want to find out what the end result would be if I had towed the truck. You know Pats fans wouldn’t have that."

So Matthew let the truck down and that's when Gronk emerged -- super thankful for the reprieve -- and posed for a few pics.

Matthew was quick to tell us ... Gronk never asked anyone to stop or offered any kind of favor. Everyone involved was just acting out of the kindness of their hearts.

Not everyone was so lucky ... a few other cars did get towed that night.

Pays to be Gronk.

Kim Kardashian and Kanye West might very well be having a baby boy -- but don't read too much into those photos of them shopping for little boy clothes.

According to our sources, Kim and Kanye are playing it really close to the vest on the baby's sex right now -- maybe they know, maybe they don't ... but they're not saying.

Kimye was seen Monday afternoon purusing the boys section in a New York boutique, so the Internet collectively figured ... they must be having a boy! But we're told Kim and Kanye were shopping for something for Kourtney's daughter Penelope, and they just happened to be drawn to items in the boys section.

Not to mention ... they are holding up clothes for a toddler, not a newborn.

Kim Kardashian will be giving birth this winter ... because TMZ has learned she is three months pregnant.

According to our sources, Kim conceived some time in March ... which means she should be popping out a little West in December.

In Sunday night's "Keeping Up With the Kardashians," psychic John Edward told Kim he saw something with the number three, but wasn't sure what it meant. We're told Kim's a believer and thinks it means getting pregnant the third month of the year.

As for the mother-to-be, Kim was seen out Sunday afternoon in New York City.

BTW ... how awesome if they named the kid South West.

Kanye West was the inspiration Friday night for the graduating class at a prestigious fashion school.

Kanye was front and center for the runway show held by graduating fashion students at L.A. Trade Tech College, we're told he went backstage prior to the event to give the students encouragement, sat in the front row during the show, and then spoke in classic Kanye style.

The most memorable line ... "When you're the best you get hated on the most."

The University of Southern California is standing behind one of their baseball players who was sued by a woman in a sex tape lawsuit ... TMZ Sports has learned.

The accuser -- a former USC student -- filed a lawsuit against Vahn Bozoian, Sean Adler and Marc Huberman ... claiming they all had a hand in recording and distributing a sex tape that was recorded without her knowledge.

In the suit, the woman claims the footage -- which featured her having sex with Bozoian -- was screened for the USC baseball team and other students in March 2013 ... and it ruined her life.

The woman claims Adler is the one who secretly recorded the video, in cahoots with Bozoian. She claims Adler then sent the footage to Huberman.

Bozoian and Adler have since been kicked off the baseball team -- and Bozoian has since left the school.

As far as Huberman goes ... a high level USC source tells us, "We investigated. The case involves 3 people. There's a reason 2 of them are not on the baseball team anymore."

Chris Brown's daughter Royalty got a phone call from her dad on her first birthday ... but a source close to his baby mama says that's it.

Sources close to Royalty's mom, Nia Guzman, tell TMZ ... Brown didn't show up for the 1-year-old's birthday, didn't send a gift and didn't contribute to the cost of the Chuck E. Cheese's shindig. Nia says her boyfriend, King Ba, paid for the whole thing.

Ba -- who's listed on the birth certificate as Royalty's birth father -- seemed to take pleasure in Chris' absence and captioned one pic of Royalty by writing, "Wouldn't Miss This Day For Anything In This World."

Slow down, Jelena fans -- yes, Justin Bieber and Selena Gomez hung out Wednesday night ... but they are not dating again. Not yet anyway.

The reunion of everyone's favorite on-again/off-again set the Internet on fire, but here's what really went down.

Pastor Rich Wilkerson Jr. -- who counts Bieber and the Kardashians among his flock -- posted a series of videos from a gathering Wednesday night in L.A. ... and both Bieber and Gomez were there.

According to our sources, the exes were cordial, but that's it. In fact, Bieber brought rumored girlfriend Hailey Baldwin with him -- another sign there's no reunion on the horizon.

We're told this isn't the first time Bieber and Gomez have been together lately -- they've both been to a few of Pastor Rich's gatherings in recent weeks.

So, no romantic sparks for now. Give it time, they'll be back together -- and broken up again -- eventually.

United Airlines has a problem with crying infants according to alternative rocker Sarah Blackwood ... who says she was kicked off a flight because her 1-year-old son got fussy -- but the airline claims the kid was a safety risk.

Sarah -- Walk Off the Earth singer -- is 7 months pregnant and says UA kicked her off the San Fran to Vancouver flight ... after less than 10 minutes of Giorgio squirming and crying. She says he fell asleep after the fit, but for the airline the damage was done. Sarah says the plane stopped taxiing and returned her to the terminal.

Sarah's fellow passengers saw her and her son get escorted off the plane -- and many of them took to social media to express their outrage over the situation. Let's face it ... babies cry on planes all the time.

We contacted United and a rep says the flight crew made a difficult decision, but made the correct one “based solely on safety concerns." The rep claims, "the child was not seated, as required by federal regulation to ensure passenger safety, and was repeatedly in the aisle of the aircraft before departure and during taxi."

Sarah's calling BS on that. On TMZ Live, she told us she was in a window seat and her fellow passengers can vouch for her that Giorgio was not cruising the aisles.

Sarah also recorded a sympathetic United employee ... who suggested she use the power of social media to put pressure on the airline.

Lil Boosie first heard big cheers from a NYC crowd, and then huge groans .. because fans watched him vomit on stage -- and he tells us it's all because he lost some very important medication.

Boosie -- a known diabetic -- says there was a miscommunication during his travel, and the bag with his meds went to Philly ... while he went to New York. He went on stage last night without getting his insulin shot.

He wants his fans to know everything's cool now -- he's got his Rx, and is on his way to Nebraska to tear down the stage.

The King of Norway met with a Norwegian guy even more famous than him .... "Deadliest Catch" star Sig Hansen.

King Harald V of Norway came face to face with Captain Hansen in a Seattle fishing village, where Sig graciously presented His Majesty with a tray full of, what else, king crabs.

The King got a VIP tour of The Northwestern, the famous Norwegian vessel.

There's a strong connection between the King and the Captain. Sig grew up in Seattle where there's a big Norwegian presence. Sig's dad, who is Norwegian, taught his son the fishing ropes at 14.

Karrueche Tran's bloody lip and vague caption might have you believing something seriously physical went down a certain someone in her life ... but TMZ has learned that just isn't the case.

KT posted the photo Tuesday afternoon with the caption, "Rough day in Chicago." While it seems like a bad domestic violence joke -- we're told she was actually referring to a photo shoot she just did in Chi-town.

Our sources say the spread called for Karrueche to play a "street fighter" type, thus the blood.

So, despite her ex-bf temporarily overreacting to her pic with Tyson Beckford -- this fight club snapshot was strictly a work thing.

Blake Griffin knows exactly what to do to convince DeAndre Jordan to stay in Los Angeles ... take him to another country ... 'cause the two Clippers studs are tearing it up in Cabo together.

The Clippers are still licking their wounds from an epic playoff collapse ... and dealing with rumors that Jordan might bolt L.A. via free agency because of a reported beef with Chris Paul.

But this weekend in Mexico, BG and DJ hit the beach and the clubs together -- and partied like they weren't gonna let a couple million dollars break them apart.

Casey Kasem's widow Jean has been cleared in the elder abuse investigation, which has lingered for a year.

TMZ broke the story ... police launched an investigation after Casey's kids filed a report claiming Jean had taken the famous DJ on a wild, multi-state car ride which compromised Casey's health, creating bedsores that became infected.

Casey died last June, and Jean took the body to Norway, where it remained for months. Police wanted it brought back to the U.S. for a complete autopsy but that never happened.

We've just learned the L.A. County D.A. rejected the case, saying Jean did a good job caring for her husband, and concluded, "The development of a bedsore by itself is insufficient evidence of abuse or neglect."

David Letterman's former employees didn't walk away empty-handed this week -- he dropped thousands of dollars hooking them up with ... wait for it ... custom-made letterman's jackets.

Letterman's final gift to his staff have the words, "Thank you and good night" scrawled across the front. Dave scooped up more than 200 of them ... according to the owner of Golden Bear Sportswear.

Dave's been buying staff swag from GBS for 15 years, and the owner tells us they were contacted last winter, after Letterman announced his retirement plan. She says Dave designed the jacket as a final gift.

GBS wouldn't divulge exactly how much Letterman spent, but the jackets run AT LEAST $300 each ... so you do the math.

Safe to say, Dave can afford it.

The biggest obstacle standing between James Harden and an NBA championship is not Steph Curry ... it's Lil B, who is threatening to put a curse on The Beard ... unless he cops to his demands.

Lil B is pissed because he thinks Harden keeps jacking his "cooking dance" when he celebrates draining a big shot. Harden has been doing it all season, but Lil B says he's watching the Western Conference Finals -- and if Harden does it again ... it's gonna be curses.

Lil B tells TMZ Sports, "If Harden doesn't tell what he is doing, which is the Lil B cooking dance, he will be cursed. He needs to stop stealing Lil B swag without showing love."

Lil B is a reasonable man -- he's giving Harden until Game 3 to give him credit, but after that he says the curse goes into effect.

Not a believer? Remember, Lil B cursed Kevin Durant earlier this year, and uhh ...he's somewhere chillin' on a couch right now.

Stir at your own risk, Harden.
