She grew up right before our eyes!

Kendall Jenner turned 18-years-old yesterday, and the aspiring model celebrated with a family dinner at Mastro's Steakhouse in Thousand Oaks.

Big sister Khloe Kardashian came without estranged hubby Lamar Odom, but Kim brought fiance Kanye West to join in on the fun. Little sister Kylie attended, as well as recently separated parents Kris and Bruce Jenner.

We didn't spot Kourtney and Scott, so we're guessing they stayed home with kids Mason and Penelope.

The whole gang donned odd masquerade-type masks, and it looked like quite the bash to welcome the teenager into adulthood.

Speaking of adulthood, various media outlets are reporting that the brunette beauty is already receiving lucrative offers to make a sex tape, and even though Kimmy K did it, we doubt Kendall is going to go down that road.

Happy birthday Miss Jenner!

Ben Affleck was in good spirits when he picked up daughter Violet from basketball practice on Sunday, and we're guessing he's still stoked that the Boston Red Sox won the World Series the other day!

Last week the 41-year-old actor returned home after shooting Gone Girl in Missouri, and while he's done filming there, there are some scenes that still need to be shot in Los Angeles and New York. After a brief break for the holidays it's back to work, as Ben will begin shooting Live by Night, which he wrote and will direct and star in. Maybe that will get him an Oscar for directing?

On Saturday Hilary Duff brought her darling son Luca to the dog park in Los Angeles and the 26-year-old singer/actress introduced him to several pups running around.

Hilary lost her beloved Chihuahua Lola back in June, so we're wondering if she's thinking about adding a new member to her family. But we're talking about a dog, not a kid, and apparently there's a rumor going around the Hil and hubby Mike Comrie are planning for a second child!

Yesterday she tweeted, "I love that I do an interview &people ask if I want more kids.. I say yes. Not now thought and all if a sudden I'm "trying" for a girl. WHAT? It's ridiculous....The only baby I'm working on is my album."

That's the first we're hearing of it, but we're glad she cleared the air!

Post by Britney Spears.

Britney Spears debuted her new single "Perfume" on Sunday, and the pop star tweeted a link to the tune and wrote, "This is like sharing a piece of my heart <3."

The song is from Brit's upcoming album, Britney Jean, and she previously admitted that several tracks cover the fallout from her split with Jason Trawick. "After having a huge breakup this year, I had a lot to say in the studio, so it was really nice to have a therapy like that and to be able to share that with my fans … so it's a real personal album," she told Ryan Seacrest back in September.

Britney sings, "I want to believe it’s just you and me / Sometimes it feels like there’s three of us in here baby / So I, wait for you to call / And I try to act natural / Have you been thinking ’bout her or about me / And while I wait I put on my perfume, yeah I want it all over you / I gotta mark my territory..."

Was Jason cheating on Brit Brit!?

Aside from Victoria Beckham, Heidi Klum might be the hottest soccer mom around!

On Saturday Heidi and bodyguard/beau Martin Kristen cheered on her sons Johan and Henry at soccer, and while little miss Leni wasn't in a uniform, she was happy to show her support for her little brothers. Of course, Heidi also took her oldest daughter shopping that day ... maybe it was a bit of a bribe too?

And with the sneakers and the torn skinnies, looks like Leni is kinda copying her mom's style! And how cuuuuute is this pup?

It's bananas! Wonder if it's a boy or a girl?

Rachel Zoe grabbed lunch with a pal in Hollywood on Saturday, and the celeb stylist flashed us a beautiful smile ... and a peek at her growing baby bump. She's been wearing a lot of baggy tunics and maxi dresses lately, and while her pregnant tummy was very noticeable at the Annenberg event last month, it's totally popped out over the last few days! Even with her tiny frame, it looks like it's finally time to make the move to maternity jeans...

Anna Paquin and husband Stephen Moyer took their adorable twins Charlie and Poppy for a walk in New York City on Saturday, and the family were clearly enjoying the crisp autumn weather.

Paquin, 31, and Moyer, 44, welcomed their fraternal twins in September of 2012, and while she's eager to watch them grow up, he recently joked with People Magazine, "I think Anna’s very excited about them walking and I'm like, 'Just wait - our lives are over once that happens!'"

“It’s just all so amazing — they had a tough start,” he added. “They were early and it was touch and go there for a while and so anything is amazing. Spitting up the first solid food is just fantastic!” We love that he has a good sense of humor about it!

A bundled up Madonna went to Kabbalah in New York City on Saturday, and it looked like she had hopped off a horse before attending the service. Glad to see that she's riding again after that nasty fall she had in 2009 in the Hamptons ... and the other tumble she took back in 2005 that put her in the hospital!

We're not sure how Lourdes was able to skip out, but we spotted the aging pop star's other kids Rocco, David and Mercy tagging along. And boy, did Mercy and her big brother seem excited to be moving on with their day!
