Happy birthday, little guy!

On Friday, Kim, Khloe and Kourtney Kardashian got together to help celebrate her son Mason's third birthday in Miami. He's a growing boy!

Kourtney's baby girl Penelope, along with Scott Disick, joined in on the festivities as the family first went to Gold Coast Railroad Museum before dining at Serendipity afterwards. We bet he just loved all the attention!

All black everything, huh?

Justin Theroux's wardrobe took a turn for the dark side on Friday as he donned all black attire as he headed to a studio in Hollywood. Even his backpack and Mercedes Benz matched!

The 41-year-old actor/screenwriter, who's engaged to Jennifer Aniston, could be in for a year end surprise as there have been reports of the 43-year-old actress possibly sporting a baby bump. Aniston even added to the speculation last Sunday at her engagement party when she passed on sushi and her favorite alcoholic beverages. Maybe there's some truth to the reports after all!

She's lightening up!

On Friday, Jennifer Garner kept things moving as she flashed a friendly smile while wearing a bright yellow and orange sweater as she got some shopping done in Brentwood.

The 40-year-old actress had her hands full literally as she carried her adorable daughter Seraphina to her karate class prior. They sure know how to make any task fun!

Guess they're back together!

Yesterday, Kat Von D and Deadmau5 looked cozy as the two walked arm in arm as they went to grab lunch in Beverly Hills.

The couple, who got back together after a brief split, seem to be doing well... well enough for the 30-year-old tattoo artist to let her DJ beau give her a tattoo!

"Watching @deadmau5 do his first tattoo... "Look Mom, I'm a Tattooerist!" Kat joked via Twitter earlier in the week. "My new tattoo may look like a drunken third-grader did it, but I sure do LOVE it!! Thank you, Joel! ❤." Sounds like he did a bang up job!

A girl's gotta get her makeup!

Rihanna decided to dress down a bit as she wore a grey printed sweater with a pair of black shorts to do some shopping at Saks in Beverly Hills.

The 24-year-old entertainer loaded her basket with various products as she made her way through the store while greeting and hugging fans and onlookers.

Also, it's been reported that Simon Cowell is planning on meeting the Diamonds singer to offer her a job as a judge on his X Factor show. Wonder if she'll take it?

They are angels!

On Friday, Kate Moss and Candice Swanepoel struck some sexy poses as the two ladies landed in St. Barts for a Victoria's Secret photo shoot.

While the 38-year-old Moss was busy with her part of the day, Swanepoel showed off one of her secrets as she got an extra "lift" in the form of some padding to accentuate her cleavage! Even models need some support!

Hurry hurry!

Nicole Richie probably put on about 4-5 layers of clothing on Friday as she navigated her way through a frigid L.A. day to make a stop at the gym. Now that's dedication!

The 31-year-old fashion designer recently received some lofty praise from her better half Joel Madden as the two celebrated their second anniversary.

"Special dedication to my wife. We just spent a few days off the grid celebrating our 2nd wedding anniversary," the 33-year-old Good Charlotte frontman posted to his Tumblr account earlier this week. "Sometimes I keep it to myself and sometimes I can’t help myself and I gotta tell the whole world how much i love her. This is one of those times. I can’t help it. I feel like the luckiest man alive to have my wife and kids. When the world outside breaks me down, they build me back up. Hope everyone out there finds this kind of love."

What an adorable couple!

She's so caring!

Last night, a bundled up Katie Holmes braved the cold New York air to bring Suri and a friend together for a play date and the doting mother not only carried her little girl but her friend as well!

The 33-year-old actress has been busy performing in the play Dead Accounts but it's great to see that even Broadway won't stop her from being a hands on mom!
