Birthdays

Kim Zolciak's little girl is now a grown ass, pistol-packing mama, and her mom wouldn't have it any other way ... TMZ has learned.

Brielle Biermann turned 21 on Sunday, and when she got home on Monday ... Kim was waiting with her gift -- a brand new customized Glock 43, complete with rose gold slide. Brielle seemed a little nervous around the weapon at first, but Kim said it's important for her to have it ... now that Brielle's living in her own condo.

We're told Brielle's practiced at a gun range before. She doesn't have a license yet, but Georgia doesn't require one if it's stored in a home, car or place of business.

BB also got some pieces of art, which look like molds of topless women, and set Kim back $5,550 each! The handgun was a relative bargain at just $1,300.

The Floyd Mayweather 41st birthday extravaganza continued on Sunday -- featuring Drake hitting the roller skating rink while his own music played in the background!

It was the 3rd major event for Floyd's birthday -- and maybe the most fun -- as the TMT crew took over at World On Wheels in Los Angeles for an old-school roller skating party.

Floyd tore it up in his Nike skates (as usual) ... and Drake didn't do too bad, either -- casually circling the rink in his in-line skates while the DJ played his hit, "Right Hand."

Afterward, Drake hit the arcade section -- and battled it out with the basketball free-throw game.

Floyd seemed to enjoy himself, too -- telling TMZ Sports he wants to keep the party going until 2019!!

He also bragged about his new 2018 Rolls-Royce ... which hasn't been released to the public yet.

J Lo went all out for her twins' 10th birthday party ... and she took REALLY good care of the people who helped throw it.

Jennifer put on a bash for more than 30 guests at the Sugar Factory in Las Vegas Thursday night to celebrate Max and Emme's bday. We're told the party arrived around 5 PM and threw down for FOUR hours ... and made good use of their time.

Well-connected sources tell us the bill was $7,500 and included custom cakes for each child -- red velvet Mario Bros. cake for Max and chocolate sloth cake for Emme. They also gorged on virgin gummy worm goblets, and a King Kong Sundae ... with 24 scoops of ice cream topped with sparklers!

Rihanna celebrated hitting the BIG 3-0 Tuesday night in NYC, but it was less of a bad girl RiRi party and more of a super formal Miss Fenty affair. Hey, she's maturing.

The fete for her closest friends and family was held at The Pool and Rihanna arrived in a fuchsia gown. Also in attendance were her mom, adorable goddaughter, best friend Melissa Forde ... as well as Paris Hilton and fiance Chris Zylka, and Toni Braxton.

Her Saudi billionaire heir boyfriend, Hassan Jameel, was noticeably absent from photos.

Scottie Pippen ain't playin' in the All-Star Game this weekend, but he already scored ... a freakin' awesome $30,000 luxury Swiss watch -- at a celeb packed party last night.

Haute Living and Larsa Pippen threw Scottie a party at Bungalow 1 at Chateau Marmont in L.A. to celebrate his Hall of Fame career.

Scottie -- along with guests like Kourtney Kardashian, Ludacris, Omarion and L.A. Reid -- ate (steak and salmon) and drank super expensive Louis XIII cognac.

Best part of the night (at least for Pip) ... when HL presented him with a Roger Dubuis Titanium Excalibur 45 timepiece -- a watch they tell us goes for $30k.

Now Scottie's got a watch to go with those 6 rings.

A good chunk of the cast of "Black Panther" got together to ring in one of their co-stars' 40th birthday ... but they probably had more reason to celebrate than just that.

Danai Gurira -- who plays Okoye in the upcoming film -- turns the big 4-0 Wednesday, but she and her cast members rang in her fab 40s on Monday night in NYC instead.

They were partying it up at the Boom Boom Room atop of The Standard, High Line hotel -- and from the looks of these shots ... it appears most of the major "Black Panther" actors were there, sans Michael B. Jordan.

Prince Jackson's legal today, and his kid sis is celebrating his 21st birthday by giving us a super rare look at them as playful toddlers.

Paris Jackson posted this video of herself and Prince goofing around, dancing to Notorious B.I.G.'s "Juicy."

Here's what's so cool about this video -- Michael Jackson was famously protective of his kids' privacy ... covering their faces in public and almost NEVER revealing family moments like this.

Paris included a sweet message to her big brother and "role model," telling him ... "No matter where we are in the world and in life, my home is with you and the little guy. i love you so much, gooko. i’m so proud of you. happy birthday."

Chloe Grace Moretz turned the big 2-1 this weekend, and promptly turned up by rubbing on a dude that wasn't her boyfriend, Brooklyn Beckham ... but she probably gets a pass.

Chloe hit the town Saturday night for he 21st birthday by making a brief (but eventful) visit to The Abbey in WeHo with a few girlfriends ... sans 18-year-old Brooklyn. It appears the couple did recently celebrate together, but he obviously couldn't tag along for the bar hop.

As for Chloe, an eyewitness tells us she and 4 pals showed up around 10:30 PM and stayed for about half an hour. And what a half hour it was -- Chloe and her girls ordered some drinks and then got on the dance floor ... eventually calling over a nearby go-go dancer.

Kylie Jenner and Travis Scott were not stumped when it came to choosing their baby's name, and we know that because of the blanket purchased for them in late January.

Sources tell us ... Kylie was showered with lavish gifts from Petit Tresor in Beverly Hills, and one item was a light grey baby alpaca blanket from a Kardashian sister.

We're told the blanket was customized to be XL-sized with "Stormi" embroidered on it in black, block lettering. As we reported ... Kylie's kiddo was born February 1.

Our sources say the blanket's just one of the high-end gifts the family bought for Kylie/Stormi at the store. Caitlyn Jenner apparently dropped around $3,000 on baby stuff.

The items range from diaper bags at $250 a pop -- one for both Kylie and Travis -- to a $1,500 black and white stroller and a $1,000 white rocking sheep ... made from real sheepskin.

Adele did her best Dolly Parton impersonation ... and it's now Dolly approved.

The "Hello" singer played dress up to virtually become the iconic country star -- blonde wig, pantsuit, and lots of cleavage ... while clutching a guitar.

Adele gave Dolly major props with the caption ... "The effortless queen of song, Dolly Parton! We love you! We wish We could possess an ounce of your ability."

Unclear why exactly Adele's shouting her out right now -- although it was Dolly's birthday a little over a week ago. Whatever the occasion ... it caught Dolly's attention.

She responded to Adele's post with some love, saying ... "And I will always love you!"

Yes, that's Dolly's.

Ansel Elgort practically recreated a scene from his blockbuster film this weekend -- except this time, he actually belted out the words ... and it was just as charming.

The "Baby Driver" star hit up a high school pal's 23rd karaoke birthday party Saturday night with his GF, Violetta Komyshan, in NYC -- where he stepped up for at least a couple songs.

Ansel sang along to Khalid's "Location" and The Temptations' "My Girl" -- seemingly trying to channel his inner Baby from the flick ... and we gotta say, it's almost spot-on.

It's a little hard to tell through the group sing-along here, but this dude can actually croon. Just ask James Corden and Jamie Foxx.

She was a long shot to make it this far, but Fiona the hippo turned 1 year old Wednesday ... and the Cincinnati Zoo is having a phat fat celebration!

You'll recall, Fiona was born 6 weeks premature and weighed a mere 29 pounds -- a record for any hippo born in captivity. The good news is she's a very healthy 600 pounds one year later.

Naturally, Fi got a cake for her bday. No ice cream cake though ... strictly fruits and veggies, but she's a herbivore so it's cool. She's so damn cute, we'd almost forget the whole thing about hippos being seriously deadly animals. Almost.

Zayn Malik didn't let a porn site's tweet rub him the wrong way ... oh, far from it.

The "Pillowtalk" singer was leaving Gigi's apartment Wednesday in NYC where a bunch of photogs were stationed and had just a few quick seconds to get him to respond to Pornhub's birthday tweet.

And bravo to the 2 photogs who had the testicular fortitude to ask Zayn about it -- first by one guy who wondered how the Pornhub subscription's going and then by our very own guy asking a brilliant -- and much-needed -- follow-up question.

Betty White's trending online, but don't worry ... it's for a great reason -- her 96th birthday!

Betty's been one of Hollywood's hardest working leading ladies for years, but today she's taking it easy. A rep for the TV legend tells us ... Betty's relaxing Wednesday for her bday and plans on having a low-key dinner tonight at a friend's house.

As you'll recall ... White worked on her birthday when she turned 95, prepping for a guest spot on the sitcom "Young & Hungry." No such projects this time around, but we're told she's in great health and as spry as ever.

Happy birthday, Betty!!!

NHL superstar Connor McDavid is FINALLY legally allowed to drink in America ... and he celebrated by blowing it out at a Vegas nightclub -- with the guys from The Chainsmokers.

The Edmonton Oilers captain hit up XS Nightclub in the Encore hours after beating the Vegas Golden Knights in an overtime thriller ... and got the V.I.P. treatment with a massive welcoming party.

The better news for McDavid ... the Oilers don't play again until Saturday -- so he's got an entire week to celebrate (and recover) before going back to work.

Zayn Malik's now under the watchful eyes of Gigi Hadid ... if that new ink's really her eyes tattooed on his chest.

The former 1D singer celebrated his 25th birthday over the weekend and Gigi posted this video of her BF ... shirtless and bustin' a move. But a closer inspection of his chest (not that we needed an excuse) shows off the new eyes tattoo that looks eerily similar to Gigi's.

Look at 'em side-by-side ... the resemblance is uncanny. Eye think we've got a winner.
