Party All The Time

Serena Williams can drop it like it's hot ... on the grass and in the ballroom.

Serena -- celebrating her record-tying 22nd Grand Slam -- wore her Sunday best at The Wimbledon Winners Ball at The Guildhall in London. Serena was in hot demand ... she also hit up Lewis Hamilton's British Grand Prix party.

Nick Young's got a cold, hard fact for his baby mama -- Swaggy P's single and completely unattached, even though he knocked her up a second time.

Sources close to the NBA star tell TMZ Sports ... Nick and his ex, Keonna Green, are NOT back together. If you'll recall ... Keonna told US Weekly she wasn't apologizing "for being in love with a man who I have a lot of history with." It appears that's exactly where Nick wants to keep it -- in the history books.

We're told Nick's living it up in the single lane and wants to keep it that way so he can concentrate on the upcoming NBA season. Nick's living alone in the house he used to share with Iggy. Keonna's NOT living there.

As for Iggy'z one-finger salute the other day ... Nick's not trippin.

Jon Jones is causing major headaches outside the UFC -- a Las Vegas hotspot is also scrambling to clean up a financial and marketing mess.

Tampa Bay Buccaneers player Louis Murphy was so drunk and confused about why he was locked in a museum, he called 911 and he's now made the Hall of Fame ... for 911 calls.

In the call obtained by TMZ Sports, the wide receiver tells the dispatcher he was a groomsman at his friend's wedding at the Flagler Museum -- but "got kinda drunk," and accidentally fell asleep in a garden and got locked inside.

29-year-old Murphy said he cut his hand while trying to break through a door to freedom. You'd think a guy who uses his hands for a living would be pissed about that, but no ... Murph was more upset his friends were somewhere partying without him.

He was clearly still wasted. Just listen. So good.

Museum security found him and cops showed up around 1:15 AM, but agreed no criminal charges would be pressed because Murphy agreed to pay for the door repair costs.

Ciara and Russell Wilson are putting an end to any speculation about what went down in their hotel suite.

Luol Deng celebrated his arrival in Tinseltown the way any new Laker should ... thots, bottles and models ... hitting a Hollywood night spot and turning up Tuesday night.

We got Deng leaving 1 OAK in West Hollywood -- a spot regularly frequented by the Kardashians, Beibers and Rihannas of the world -- around 2:30 AM, telling us he definitely had a great time.

Deng wasn't the only freakishly tall guy turning up ... Andre Drummond and Jimmy Butler were also there ... and with the money the NBA's giving out these days, we're guessing a lot of people drank free.

Kevin Hart's call to action "Get f***** up with me!!!" ... that's what he told his boys in Vegas, and his birthday bash looks a lot like a bachelor party.

Kevin's been in Vegas for a few days and partied at Omnia Tuesday night, when he told the crowd, "I'm getting married."

Kev's been engaged to Eniko Parrish for 2 years.

Marriage ... it's in the air.

1:08 PM PT: Kevin posted on Snapchat he's super hung over ... we can only imagine.

Ciara's bachelorette went down 2 weeks ago in Vegas ... and no one connected the dots.

Ciara's BFFs, Serena Williams and Kelly Rowland, flew in for the weekend rager at the Wynn hotel. The crew -- about a dozen deep -- all agreed to keep it mum. Some signed NDAs.

As for what they did ... they hung at the pool, went to Intrigue nightclub, and also took in the aquatic show Le Reve.

Brazilian soccer star Neymar was partying at a nearby bungalow and stopped by to say hi.

TMZ broke the story ... Ciara and Russell are set to take the big plunge Wednesday in Liverpool.

"Love & Hip-Hop: Hollywood" star Mally Mall got a stoner's dream gift for his 38th birthday ... a 4-foot blunt disguised as a weed sword, and he smoked it all at his Ace of Diamonds birthday bash while shooting out $50k from a laser gun.

The mega-joint was a gift from B-Real of Cypress Hill. The two are actually partners in the weed biz and their hallmark is packaging joints in creative silhouettes.

We're told B-Real rolled about 3 oz of weed into Mally's present ... totally legal in California where anyone with a medical license can possess up to 8 oz. As for the price ... $900 since it was packed with M&M Cookies -- not the candy, but the award-winning weed strain.

As it turns out ... it still wasn't enough to go around, so they sparked another blunt, this one shaped like an uzi.

Fireworks at Nick Young's house Monday night ... with the NBA star throwing a MASSIVE party at the home he shared with Iggy Azalea in what appears to be a public declaration of his independence.

Kyrie Irving says Kevin Durant to the Warriors is a GREAT MOVE ... at least for Golden State.

Conor McGregor is gonna be working in Vegas during UFC 200 weekend -- just not in the Octagon.

Instead, he'll be hosting a post-fight party at a massive nightclub at the Wynn Hotel ... TMZ Sports has learned.

McGregor has signed on to host an "action packed evening" at Intrigue nightclub -- with special guest DJ Konflikt.

Of course, McGregor was supposed to be FIGHTING that weekend and making $10 MILLION. Instead, he'll be slamming whiskey for a lot less.

The Game threw his son, Harlem Caron Taylor, a 13th birthday party that probably made his friends cry.

The rapper got a gaggle of celebs to shout-out birthday wishes ... Lil Wayne, Diddy, Kendrick Lamar, Kourtney Kardashian and Floyd Mayweather... and the list goes on and on.

Ray J also came through ... with custom Scoot-E-Bikes.

Today is July 1st ... or as Johnny Manziel calls it -- the first day of sobriety!!

LeBron James, Dwyane Wade and Chris Paul are all partying on a yacht off the coast of Spain -- and having a BLAST!

Kyrie Irving says allegations that his yacht party was a "No Black Girls Allowed" event is complete BS -- calling the rumors complete "nonsense."

The Cleveland Cavs star came under fire from social media trolls who saw the footage of Kyrie on a boat with a bunch of women ... many of whom were white.

Now, Kyrie is firing back at the critics -- saying, "I'd never think I would have to address something as ridiculous as a yacht party, but I wasn't raised to discriminate against any race let alone any race of women, especially my own."

"I was raised by the black women in my family and for me to be connected to some nonsense like a 'No black girls allowed' party is embarrassing and an inaccurate portrayal of who and what I represent as man."

Irving apologized to the people who were offended without knowing the facts -- but says, "that story has no truth to it and I wanted to clear the air on all of this B.S."
