Birthdays

Not many people can say the best hoops player on the planet sang his heart out for their birthday ... but that's exactly what LeBron James did for Anthony Davis on his big day!!!

... and the vid is hilarious!!!

The Brow is officially 27 years old on Wednesday ... and LBJ made sure his teammate knew he didn't forget about AD's cake day ... belting out a special rendition of "Happy Birthday" in the locker-room.

"Happy birthday, AD ... happy birthday, homie ... happy birthday, my guy guy-y-y-y-y" the King sang with all his might.

It's worth noting ... LeBron is one of the greatest basketball players of all time, he's killing it in Hollywood and has made a huge impact on lives in his hometown of Akron, Ohio.

With that being said ... singin' ain't his thing.

But, hey, it's the thought that counts ... and AD loved it!! The guy even pretended to be embarrassed at the end and threw his towel at James.

HAPPY BIRTHDAY, AD!!

Madison Beer ruffled her own feathers on her 21st birthday ... and it was one helluva view.

The singer celebrated her big 2-1 Thursday night in WeHo in front of a star-studded crowd at Delilah nightclub. All eyes were on Madison ... she slayed in a baby blue, bejeweled, carnival-themed costume.

Madison had some stiff competition though in the attention department ... as in the birthday cake.

Baby blue seemed to be the color of the night as Hailey Bieber went chic business with high-knee leather boots. Hailey's hubby had a big hand in practically launching Madison's music career. Remember, it was Justin who 8 years ago tweeted a YouTube video showing then 13-year-old Madison belting out Etta James' "At Last."

The rest is history.

Luka Doncic might have lost his Mavericks game on his 21st birthday ... but he DEFINITELY won the after-party!!!

TMZ Sports has learned the NBA superstar got after it Friday night for his bday despite losing to the Heat ... hitting up Miami hot spots with his Mavs teammates and other celebs.

We're told Doncic and the guys got dinner at Papi Steak in Miami Beach before ultimately spending the night at Club LIV.

And, you can see in photos we obtained of the festivities ... Doncic was having a blast -- even at one point getting some partying in with Bad Bunny!!

We're told Mavs owner Mark Cuban threw an especially big bash for his team's best player ... taking over LIV's stage area and popping champagne all night.

As for how the hangover went ... the Mavs were off Saturday -- but Luka still took Dallas' game off against the Timberwolves on Sunday.

The team says it was because of a previous thumb injury ... but we're not so sure we're buying that.

Justin Bieber turned 26 this weekend -- and as much as you might think the guy had every reason to cut loose ... he kinda did the exact opposite when it was time to make a wish.

The Biebs' party went down Saturday night at Delilah in L.A. -- this after a reported 1-on-1 romantic dinner with the missus, Hailey -- where a bunch of their pals came out to help him celebrate the big 2-6. It looked like a sweet shindig -- there was a live band, drinks being passed around and, of course, lots of pastry sweets ... including candle-lit cupcakes.

He had a cake to himself though, and as everybody sang him "Happy Birthday," Justin looked a little ... dare we say, somber? Yes, some of that -- but mostly content and chillaxed.

He had Hailey right in front of him, naturally, and it appears he kept his eyes mostly on her the whole time. Clearly, the married couple is head over heels to this day. He was later seen cradling her from behind, and they snuck in some smooches where they could.

Even with a ton of cameras on them, they didn't seem to care. Justin and Hailey just couldn't keep their hands off each other as they hugged, kissed, swayed and canoodled. Young love at its finest, right?

Now, just to be clear ... it wasn't all lovey-dovey and heart eyes all night -- JB DID get down and bust a move at different points in the party. He also got on the mic for a bit, but for the most part ... Bieber seemed to be acting pretty freaking responsible and playing the good hubby all night.

Taylor Swift and her boyfriend, Joe Alwyn, have been seen out in public before -- but on his 29th birthday ... they seemed to go above below and beyond to hide for some reason.

Here's the deal ... paps got photos of these two goofballs Saturday walking out of London's Bob Bob Ricard restaurant, completely covered in umbrellas. They were following each other out to a waiting SUV and a flock of photogs ... and clumsily boarded the vehicle.

Fact is ... we're being told this is supposed to be Taylor and Joe -- and hey, it was the guy's 29th birthday on Friday -- but you never really see them, so it's hard to say for sure.

That said ... one of T-Swift's BFFs, Ed Sheeran, was also seen leaving the restaurant shortly afterward -- so it wouldn't be outside the realm of possibility that these two umbrella-heads were, in fact, the man and woman of the hour. Plus, frankly, this is kinda Taylor's M.O.

She famously tries to hide from lurking paparazzi, sometimes going to extreme lengths ... like when she put up an entire makeshift sheeted walkway while serving as a bridesmaid in 2017. Some of the fans that had gathered outside even booed the cloaked gesture.

Now, when it comes to Joe ... Taylor's also been pretty low-key about being spotted out with him -- although, they absolutely have been seen holding hands and packing on a little PDA.

They made a run for it once while hitting up the Jingle Ball concert in NYC, not giving paps a chance to snap some decent shots. Now, they appear to have upped the ante more so.

Kim Kardashian is the queen of birthday surprises, because she just took Jonathan Cheban's birthday cake to the next level, as in ... supersized snack!!!

Here's the deal ... Jonathan, or rather Foodgod, celebrated his 46th trip around the sun Friday, and had ordered up a cake from Divine Delicacies Cakes in Miami. Kim caught wind of it beforehand, called the bakery and requested a supersized version as a BIG surprise.

The final product is a sight to behold ... it stands a whopping 5 feet tall and is completely edible! Well, aside from the Swarovski crystals spelling out FOODGOD on top. Damn thing even glows in the dark with 24 karat gold accents.

Each layer of cake is a different flavor -- there's vanilla rum with dulce de leche, vanilla with vanilla bean custard, chocolate with chocolate buttercream, red velvet cream cheese, cookies and cream, guava cream cheese, coco and guava and Baileys. Ya full yet???

All told, the cake took 16 hours to complete and cost Kim about $10k.

Foodgod was caught completely off guard when he picked up his order, and the bakery even decorated the front entrance just for him.

It's good to be an FoK!!!

Paris Hilton took over the dance floor at her birthday party, as she was really feeling the vibes of a hit Britney Spears track ... this is "sliving" at 39.

The famous heiress had a huge shindig Thursday night to celebrate the final year of her 30s, which she entered earlier this week. The bash was held at "Slivington Manor" in Beverly Hills -- if ya don't know, "sliving" is a term coined by Paris combining "slaying" and "living."

Sounds like a lot to live up to, but Paris took the reins and didn't hold back ... even if she was flying solo as she moved and grooved -- and even twerked -- to a bunch of hit tracks.

Along with "... Baby One More Time," her dance playlist included 50 Cent's "In Da Club" and Miley Cyrus' "Party In the U.S.A." ... like all good parties should.

As you can see, Hilton's party decor featured giant balloons, flowers, lots of pink stuff and #sliving signage ... along with a tie-dye convertible BMW. There were also treats and drinks galore and a star-studded guest list.

Among the partygoers ... French Montana, Machine Gun Kelly, Rita Ora, Farrah Aldjufrie, Sommer Ray, Dorothy Wang and Stephen Dorff. Two Kardashian sisters -- Kim and Kourtney -- also showed up, albeit briefly. Of course, her sister Nicky and mom Kathy were there too.

Madison Beer splurged for her personal assistant's 30th birthday gift ... and we ain't talking expensive booze or jewelry, more like luxury wheels.

The surprise reveal went down Monday night in L.A. after the singer and some friends celebrated her assistant's birthday. When dinner ended, Madison handed her assistant a bag, but it turned out to be empty. It was also a ruse.

Check out the vid ... you can see Madison pull out a key fob to a brand new Mercedes-Benz C300. Suffice it to say ... Madison's assistant was stunned and damn near speechless.

Helluva gesture, especially 'cause Madison knew about her assistant's car trouble for a while. We're told her assistant's 12-year-old whip kept breaking down. It's a car she used a lot to run Madison's errands and whatnot. Madison also knew her assistant's dream was to one day own a white Benz. Madison delivered, and then some ... a white-on-white model that tends to run upwards of $50k.

Goes without saying, Madison is super close with her assistant, and knew this would blow her mind. She was dead-on, as you can see in the video -- which also reveals a sweet new nickname for boss Beer.

City Girls rapper JT says she "spent a car" on Yung Miami's birthday gift, but clearly she was being modest -- it's easily the price of a house!!! Or maybe she drives really pricey cars.

JT surprised her partner with some shiny bling for her 26th birthday Tuesday ... leaving YM305 speechless. We're told the gift -- 2 months in the works -- was delivered Tuesday night.

The chain is a baller 130 carats ... and features everything YM's obsessed with -- diamonds, music notes, money, Chanel and her kids' names. Celeb jeweler Elliot Eliantte was the artist behind the masterpiece.

JT said on social media ... "Happy birthday to my EVERYTHING. I spent a car on this I F***ING LOVE YOU & if a b*tch ever think otherwise they crazy!!!! B*tch you love diamonds Chanel & your kids.... it's all there! Pop your sh*t!!!!"

YM's reaction can be summed up in 2 words. Speechless and tears.

As we first reported ... Miami hooked up JT with some serious jewels last year to celebrate JT's prison release.

Remember that "Friends" episode? The one where Jennifer Aniston turns 51 and parties with some of her closest friends?? Well, allow us to jog your memory.

The actress celebrated the big 5-1 Tuesday night at the Sunset Tower Hotel in West Hollywood, where she made a sneaky quick entrance ... but her pals were slow to trickle out. Just a small handful of those in attendance ... her BFF and former "Friends" costar, Courteney Cox, jewelry designer Jennifer Meyer, Kevin Nealon and Chace Crawford.

We're sure there were way more guests that might've left through other exits ... Jen's pretty popular in Hollywood, if you hadn't heard. Has been for years now, in fact.

Speaking of the bday girl ... an interview she did with Interview Magazine was released Wednesday, featuring her on the cover looking as gorgeous as ever. There's also a photo spread inside -- which is sure to remind you why you watched "Friends" all those years ago.

Just kidding ... it was a good show. But, truthfully, JA made it all that much better. And hey,  now she's on another series, "The Morning Show," that shows off her chops in a drama.

Here's what you get for the man that has everything ...

Cristiano Ronaldo was surprised by his smokin' hot GF with a brand-new Mercedes for his 35th birthday ... and TMZ Sports has learned the whip cost nearly $1 MILLION!!

The insane present was given to Ronaldo after a dinner date in Italy on Wednesday night ... and CR7 -- a dude who's worth a BAJILLION dollars -- seemed legit stunned by the gift!!

The ride -- reportedly a 1-of-10 vehicle -- was draped in a red bow ... and Ronaldo's friends helped him celebrate it by dousing him in confetti and a rendition of "Feliz Cumpleanos."

Ronaldo's longtime GF, Georgina Rodriguez, said of the present in Spanish, "Congratulations to the man of my life! I can't wait to transport our love with your gift."

The ride is seriously insane ... it's got 800 horsepower, goes 0-to-60 in 2.9 seconds, and reportedly costs around $875,000!!!

Of course, Ronaldo is a huge car collector ... the dude reportedly owns around 20 super fancy rides -- so Georgina definitely won this bday.

Dog the Bounty Hunter's tumultuous week of family drama was capped off with a birthday dinner filled with emotion ... but interestingly, without ONE key person.

Sources close to the reality TV star tell TMZ ... Duane celebrated his 67th birthday Tuesday with a small group of family and friends at a Denver Benihana. We're told everyone at the table shared stories ... including some about Beth Chapman, which made Dog a little weepy.

The guests included his daughter, Bonnie and her husband, his son, Garry, his advisor and Justin Bihag ... one of his employees who's run into legal trouble lately.

TMZ broke the story ... Justin was arrested for allegedly violating probation. Dog's other daughter, Lyssa, reportedly outed Justin to cops, but she's having some legal trouble of her own now.

It's a messy situation, and it all ties back to Justin's mom, Moon Angell.

In case you haven't heard, Moon is a longtime friend of Dog and Beth who's been accused of starting up a romantic relationship with the guy in the wake of Beth's passing. They've both denied anything physical is going on, insisting their relationship is platonic.

They even went on the 'Dr. Oz Show' and put on a "test" proposal to definitively confirm nothing fishy's going on between them, despite Lyssa's suspicions.

Interestingly enough, Moon was NOT at Dog's birthday dinner -- even though Justin was. We're told Dog loves the kid like one of his own and continues to look out for him.

Kylie Jenner and Travis Scott pulled out all of the stops and more for Stormi's, second birthday.

The party was insane .... a crossover between "Trolls" and "Frozen." Check out the video and you'll see the party we never had.

As for who showed up ... Hailey Bieber, Kourtney, Khloe and Kim Kardashian, Kris Jenner and Corey Gamble, Sofia Richie, Caitlyn Jenner and Sophia Hutchins, John Legend, Chrissy Tiegen and Luna, Kimora Lee Simmons, Lalika and Khadijah Hagg, Rose Bertram, Jaden Smith and Draya Michele.

If this all rings a bell, this is the second annual StormiWorld, and the parents claim this one's better than the first.
