Party All The Time

Training camp might be over, but turn up season is just beginning for Floyd Mayweather ... 'cause TMZ Sports has pics of the money man's triumphant return ... to the clubs.

Floyd put his famous party ways on hold while he trained for Manny, but now that that's in the bag, he's back out ... hittin' up Too Short's bday bonanza at club Lure in L.A. on Friday night.

Mayweather wasn't the only big name clubbin' that night -- Snoop was there ... as well as Diddy's sons Justin and Quincy. L.A. party gods Branden King and DJ Dirty Draws kept the crowd moving.

We're told Floyd played it cool the whole night ... not drinking or partying too hard ... maybe because he says he wants to fight again in four short months.

Chris Brown's birthday celebration on the Vegas strip had bottles poppin', hot chicks dancing, and ... absolutely adorable little baby videos.

Yeah, Chris' 26th bday party at Drai's was way different from his others, because this one featured home vids of Royalty on a big screen -- and you've gotta see the look on Chris' face ... daddy's totally fallen for his baby girl.

The video is pretty wild for a few reasons -- Chris hands out Ace of Spades bottles to fans in the crowd ... Chris shows off his badass dance moves ... AND Chris spins and goes flying off the stage!

Breezy also got the champ to come out -- Floyd Mayweather Jr. showed up flashing a tiny bit of the more than $200 mil he earned at the office last weekend.

Selena Gomez must be exhausted ... 'cause the chick was running all through Justin Bieber's mind during Monday night's Met Gala -- at least that's how JB made it seem on the way out.

Justin and Selena have been broken up for months, but as he left the ball -- which Selena also attended -- Biebs went out of his way to throw out a line that was loaded down with bait for his ex-gf.

Watch ... he absolutely, almost desperately, wanted to make a point about SG's dress last night.

Word on the street is she just broke up with Zedd, so uhh ... never say never?

Then again ... Justin didn't seem to be losing sleep over her while partying with Leo DiCaprio at Rihanna's after-party. #TurnUp

The guy who organized the San Antonio Spurs post-Game 7 mega-bash was their very own coach -- who paid for a fancy steak dinner, drinks and a party bus to thank his players ... TMZ Sports has learned.

Our Spurs sources tell us ...Coach Gregg Popovich wanted to show his appreciation to his players after they were eliminated from the playoffs Saturday night ... so he organized a night out in Hollywood.

We're told he set up a post-game steak dinner at Mastros in Beverly Hills ... and paid for EVERYTHING (and this place sure as hell ain't cheap).

Afterward, Pop hired a party bus to chauffeur the guys to Project Club L.A. -- and encouraged the team to "take their minds off the game and let loose" ... not wallow in their sorrows.

The guys did just that ... some harder than others ... and as we previously reported, Tim Duncan had to carry at least ONE of his over-intoxicated teammates back to the bus.

Pretty cool boss.

Stephen A. Smith is obviously a close personal friend of 50 Cent ... 'cause TMZ Sports has video of the ESPN host taking the stage with Fiddy this past weekend in Vegas and ... it's funny in a good way.

50 was performing at Drai's Friday night when 47-year-old Smith hopped onstage for what we'd like to believe was an audition for membership in the G-Unit.

Check out the clip -- Stephen A. seems to have mastered "what the hell am I doing up here" swag ... 'cause 50 doesn't seem bothered with him being in the crew ... even though he looks like someone's uncle.

** WARNING -- VIDEO CONTAINS TIM DUNCAN SAYING A CUSS WORD**

The San Antonio Spurs PARTIED LIKE CHAMPS hours after they were eliminated ... with Tim Duncan dragging one of his hammered teammates out of a nightclub ... and TMZ Sports has the footage.

Tony Parker, Tim Duncan, Boris Diaw and the rest of the squad hit up Project Club L.A. in Hollywood on Saturday right after losing a Game 7 thriller to the Clippers.

You gotta check out the clip -- Aron Baynes was in especially rare form ... with Tim Duncan telling him to "Shut the f**k up" as he dragged the seemingly HAMMERED 28-year-old down the street.

Ass. Ass. Ass. Ass. Ass.

That seemed to be the theme at Dennis Rodman's birthday party blowout this weekend ... and TMZ Sports has all the thong'd out footage.

It all went down at Sapphire gentlemen's club in Vegas -- where The Worm was constantly flanked by a team of talented twerkaholic strippers.

But it wasn't just about lap dances ... Dennis also mingled with fans, signed autographs and took pics with anyone who asked.

Nobody was feeling Jay Z's after party in Las Vegas the way he was -- and that's a good thing ... 'cause from the looks of It Jay just wanted to be somewhere else.

Jay Z hosted, undoubtedly, the most exclusive Mayweather-Pacquiao bash at Marquee Nightclub Saturday night ... VIP tables went for $50k.

He and Beyoncé held court at their own table right on the dance floor -- but while the DJ was trying to get the crowd going, Jigga seemed to be dreaming ... of laying his head on his pillow.

Justin Bieber was amped up at Rehab in Vegas before the fight ... singing to Big Sean -- which is surprising -- and making his feelings about Manny Pacquiao clear.

Justin partied with the crowd before walking out with Floyd Mayweather, and at 33 seconds you can see him mouth the words, "f*** Pacquiao" ... he then flips the bird.

It's also interesting he's felling Big Sean, whose breaking with Ariana Grande did not go well. You'll recall he just gave her a squeeze from behind a few weeks back, which set Sean off. We're told Sean doesn't have hard feelings for Biebs ... he thinks Ariana just used him.

The Spice Girls reunited for a very special occasion -- David Beckham's 40th birthday ... and someone was noticeably absent.

Victoria Beckham threw the party in Morocco Saturday and most everyone dutifully showed up, including Emma Bunton, Melanie Chisholm and Geri Halliwell. The missing Spice -- Mel B.

Victoria posted the pic and tagged it "Spice Girls in Marrakech!" ... thing is, Eva Longoria joined for the photo.

They didn't perform, but they partied with David's family and all the other celebs.

Diddy wants to leave the fighting to the professionals this weekend in Las Vegas, so he's taking extra precautions to make sure he doesn't get into any trouble during his Mayweather/Pacquiao party.

The rap mogul is once again hosting a huge after-party for the fight at the Havana Room & Beach Club at the Tropicana -- but Diddy wants this fiesta to go smoother than his Super Bowl event ... where he got into a fight with a pissed off fan.

According to our sources, here's Diddy game plan:

-- his VIP section will be far away from normies (unlike SB weekend)
-- 20 extra security guards to watch over his VIP section
-- guards instructed to immediately toss anyone heckling Diddy

Mo money, less problems ... that's the goal, anyway.

Hours after Trae Waynes was taken as the 11th overall pick in the NFL Draft ... the newest member of the Minnesota Vikings partied from the windowwwwwww to the wall -- with Lil Jon!!

The former Michigan State cornerback hit up Studio Paris in Chicago for a post-draft party ... where he rocked the purple and gold to celebrate the fact that he just became a friggin' MILLIONAIRE!

Former "Baywatch" star Jeremy Jackson was arrested for stabbing a man, but he says it was self defense in the midst of a wild party.

Jeremy was jailed Saturday, after cops nabbed him for allegedly burglarizing an Airbnb. Police say during the arrest they realized he fit the profile of a man who stabbed a guy the day before.

Jeremy tells TMZ, he rented an Airbnb and threw a party with some women. During the shindig, he says a guy showed up, beat him up and robbed him to the tune of $2,300.

This is where it gets bizarre. Jeremy says one of the women said she knew a guy who could help him get the money back, so Jeremy told her to get him over STAT. He says the guy showed up but then turned on him and tried robbing him as well.

Jeremy says the guy pulled a gun, and in self defense he pulled a buck knife from his jeans and stabbed the guy in the stomach area and arms. The guy dropped the gun and ran.

Jeremy identifies the guy as a Canoga Park gangbanger with a clown tattoo on his face.

Justin Bieber was not welcome at the high school prom he crashed this weekend -- not by the adults, anyway -- because school administrators say he physically shoved his way into the event.

Bieber popped into the Chatsworth Charter High prom for a few minutes on Saturday night at Jim Henson Studios in Hollywood -- and the students LOVED it when JB cruised around the dance floor.

Now, this might sound a little Footloose-y ... but the L.A. Unified School District thinks Justin's surprise dance appearance put students at risk. A district rep tells TMZ, "His entourage pushed past the school's security to gain access to the dance floor" ... and administrators were worried they wouldn't be able to control the crowd.

Justin had been recording on the lot -- something the school says it was aware of ... however, they were "assured that he would not come out to interfere."

Bieber's rep tells us no one tried to stop him when he walked in at the request of a few students he met on the lot. The rep adds, "It's unfortunate they're trying to make this a negative thing. It was awesome for all the kids."

The school does acknowledge the kids had a "once in a lifetime experience" -- but adds its main concern was for the safety of the kids and Justin.

Kris Jenner allegedly swindled a homeowner who thought he was renting his home to her for a small, demure dinner party, when it was really a wild bash with loud music, a stripper and a hundred hormonal teens.

Gabriel Fedida claims in a new lawsuit Kris and her realtor made a deal to rent the Hollywood Hills house for $10k for a 15 person dinner party. Fedida says to his horror Kris used his home as the backdrop to celebrate Kendall's 19th birthday, with 100 of her closest friends.

Fedida says there was ear-shattering music, general rowdiness and strippers!

When the dust settled, Fedida says there was $101,450 in damage. He says the house is now out of commission, so with lost rent he wants $150k.

We reached out to the Kardashian camp ... so far no word back.

One Direction's Louis Tomlinson is easing back into bachelorhood ... by hooking up with multiple chicks at once -- or so it seemed when a pack of at least 3 went to his London hotel room.

Tomlinson was partying at Cirque Le Soir Wednesday night ... before the after-party moved to the Soho Hotel. Best part of the rendezvous -- the girls' walk of shame Thursday morning -- although maybe it's more like walk of fame ... when you've raged with a One Direction singer all night?

Tomlinson broke up with GF Eleanor Calder last month after 4 years together.

Everyone mourns in their own way.
