Birthdays

Kirk Douglas celebrated hitting the century mark, surrounded by a several generations of family and Hollywood friends at the Beverly Hills Hotel.

The Hollywood legend partied with his wife, his son Michael and Catherine Zeta-Jones, their kids, Steven Spielberg, Don Rickles and many more Friday night.

No word if the guests each stood up and yelled, "I'm Kirk Douglas!" -- but that would've been cool. Happy 100th!

Fun fact: The Beverly Hills Hotel opened 4 years before Kirk was born.

Aaron Paul sure loves his wife, and his space -- he's renting out a massive private villa in Thailand just for the 2 of them.

Aaron is sitting beachside in Thailand this week with his wife, Lauren Parsekian, to celebrate her 30th birthday. Rather than getting a hotel room, Aaron basically opted for a compound -- a 10-bedroom, 8-bath estate -- which usually rents for more than $5,000 a night.

We're told Aaron got hooked up from Airbnb, so it probably won't cost him that much to live like royalty. Based on his Instagram, Lauren and Aaron are toughing their way through all this luxury.

"Breaking Bad" success -- the gift that keeps on giving.

DeSean Jackson turned 30 years old Thursday ... and he celebrated by raging his face off at a D.C. nightclub ... chugging champagne, taking shots and rocking more jewelry than Tiffany and Co.

The Washington Redskins superstar hit up Sax -- a super gaudy, gold-everywhere, over-the-top club -- where he celebrated with the likes of Wale and 'Basketball Wives' star Laura Govan.

Jackson broke out his fancy jewelry and his fancy Maybach for the occasion and turned all the way up.

Our advice ... HYDRATE! Just 3 days 'til DJ takes on the Arizona Cardinals.

Steve Irwin's son, Robert, celebrated turning 13 by making his late dad proud -- cradling a baby crocodile and feeding others twice his size.

Robert's party was at Australia Zoo with sister Bindi, mom Terri and a reptile-themed bday cake that looked like some kinda hatchling -- perhaps a T-Rex embryo? One-winged Pterodactyl?

Hailey Baldwin got pampered for her 20th birthday ... and this SICK crib's all the proof you need.

Hailey got away from busy NYC and jetted off to Toronto to celebrate her birthday Tuesday in this stunning Airbnb rental, hooked up by the company.

This 4 bedroom, 5 bathroom pad is part sleek and part charming -- from its modern amenities to cozy outdoor space, it's the perfect place to get turnt. It's got a sweet lap pool, sauna, theater, elevator and a baller private garage.

How baller is it? Just ask Gigi Hadid ... she's stayed here before.

BTW ... they were drinking rose and other stuff, but it's all legal. Drinking age is 19.

It's quite a bargain too ... around $3k per night.

Kylie Jenner literally brought out the big guns to celebrate Tyga's birthday.

The couple hit up Bullets and Burgers in Vegas Saturday -- the day he turned 27 -- and they were loaded for bear. Kylie fired a Glock 17 and MP5K, while Tyga took aim with a gold .50 caliber Desert Eagle and an M16.

The firepower was so intense ... both needed someone to hold them up from the recoil.

After the bullets, they jumped on what's tabbed as the world's largest monster truck. Add burgers and fries, and that's a birthday with some serious kick.

Best of all, Tyga didn't buy anything ... so nothing was repossessed.

Goldie Hawn got the first-ever Mariah Carey and Future duet on her 71st birthday when the two rolled up to her dinner table and gave an impromptu performance of "Happy Birthday."

It all went down Saturday at Catch, L.A.'s new hot spot. Goldie's daughter, Kate Hudson, threw the dinner for about 15 of Goldie's closest. Kurt Russell and their sons, Boston, Wyatt and Oliver, were also there.

Mariah happened to be at the restaurant too, as well as Future, who was there for DJ Khaled's book release party. We're told the two wandered over for a quick chat, but ended up singing "Happy Birthday" to Goldie together.

Also there that night ... Nicki Minaj, Meek Mill, Nas, Will.i.am, L.A. Reid and Ben Savage ... so, yeah, good luck getting a table.

French Montana's lucky to have friends like The Weeknd when his birthday rolls around ... he just bought French a pricey new watch fit for Father Time himself.

French hosted a small gathering of his closest pals Tuesday night to celebrate his 32nd born day, and it looks like Abel came through as his #1 guy with a $100,000 Patek Philippe timepiece for the rapper ... diamond-studded and all.

Watch -- French can barely hold in his excitement ... The Weeknd can barely put down his phone.

Kevin Hart dropped the mic and picked up a game controller to ring in his little man's birthday.

Kevin and his ex-wife, Torrei, celebrated their son Hendrix's 9th birthday with a video game blowout at Play It Loud in Woodland Hills, CA. We say blowout 'cause the kid had more than 100 guests!

Hendrix and his crew gamed on Xbox, PS4 and Nintendo Wii consoles. Plus, he got a sweet virtual reality birthday card -- and the biggest surprise was Hendrix's favorite YouTube star, Cory Kenshin, showing up.

By the end of it all, Kev's kid was speechless and motionless ... in epic fashion.

Blac Chyna is pissed at Tyga for jacking her Ferrari birthday party plans for their son, and adding his own bells and whistles to outdo her ... and she smells a rat behind the whole mess.

A source close to Chyna tells TMZ ... she believes a production staffer on her reality show fed Tyga and Kylie Jenner all the details of her party for King -- which she spent 2 months planning. We're told Tyga and Kylie were invited to the Saturday event, but no-showed ... then threw their bigger copycat bash the next day.

Chyna says she's happy her son enjoyed the birthday double up, but as a mother ... it was a slap in the face. Plus, it's insult to injury if someone from her own show tipped off her enemy.

Co-parenting. It ain't for everyone.

Justin Bieber isn't dating a kid anymore -- his new girl, Sofia Richie, is now the BIG 1-8.

Justin and Sofia got their juice on Tuesday in North Hollywood, the day before she officially became a woman ... in age, anyway. They hadn't been seen together for about a week while Justin was overseas performing at a British music festival.

Now they're not only reunited -- they're legal! You can stop cringing.

Blac Chyna had a serious moneymaker on display for her 28th birthday party at a Miami strip club -- and we ain't talking about her ass.

Her 4-tier cake came fresh out of Dollface Delight Cakery in Miami, and we've learned biz is booming at the bakery since the high-profile gig at G5ive. Owners, and sisters, Raquel and Christina Basil tell us they whipped up their creation in 16 hours, but the hard work has paid off -- they've gotten nearly double their usual orders.

Who knew cake lovers hang at strip clubs on the reg?

The sisters say BC's cake would normally cost between $1,100-$1,300, but they only charged $500 since only the giant gold ribbon and the bottom tier were edible. Delicious buttercream cake, btw. Best of all ... BC actually got to have her cake and eat it too, since she's got a little Kardashian on the way. No word if Rob Kardashian took a cheat day.

The most popular agent in town attracted more celebs than the Golden Globes can only hope.

CAA agent Cade Hudson had a birthday bash Wednesday night at Palm restaurant in Beverly Hills. The rain didn't stop a swarm of celebs from dining on steak and lobster, including Gwyneth Paltrow, Sean Penn, Kate Hudson, Joe Jonas, Paris Hilton, Nicky Hilton, Ryan Phillippe, Bella Thorne, Seth MacFarlane, Rachel Zoe, Amanda Seyfried, Suki Waterhouse, Emma Roberts, Francesca Eastwood, Jeff Beacher,Amber Valletta and Dylan Penn.

If Cade gets 10% from all of them, that's a lot of cash ... and cake.

Raven-Symone couldn't get the real Kim Kardashian and Kanye West to celebrate with her for her big 30th birthday, so she opted for the next best thing.

The Weeknd and Ed Sheeran don't just spare change for homeless vets in the street ... they drop bills, as one lucky guy found out.

The singers happened to leave Leo DiCaprio's birthday party Wednesday night in NYC right after each other, and both were approached by a guy who said he's an ex-soldier just looking for a warm meal.

The fact it was Veteran's Day probably helped his cause ... plus, it's been a really good year for Ed and Weeknd. But ultimately, we think it was the guy's hustle that scored him some cash.

Kardashian family matriarch Kris Jenner turns 60 on Thursday ... but she certainly doesn't look it!
