Angelina Jolie and her nanny were snapped at a local park in Hollywood yesterday, and while Angie spent most of her time in the passenger seat of her black SUV, we'd recognize her adorable twins Knox and Vivienne anywhere!

But what's with the soda? I guess Brad wasn't kidding when he said he gives his kids coca cola in the morning to wake them up. At least it's diet, but still! Given how much the family likes to go to McDonald's, is that really the healthiest thing for them to be consuming?

After running errands on Saturday morning, a radiant Reese Witherspoon cheered on her son Deacon at his soccer game in Brentwood.

We still can't believe the Oscar winner gave birth to son Tennessee just one month ago! She looks amazing, and she hasn't let three children slow her down one bit! On Friday night Reese made her first post-baby red carpet appearance at the opening of the Rag & Bone store in West Hollywood, turning heads in a blue dress and black booties.

Fun fact: Reese's hubby Jim Toth wore a gray Rag & Bone suit for their 2011 wedding at her estate in Ojai, California.

We're not exactly sure what Christina Aguilera was dressed as on Saturday night, but we're glad she's still madly in love with beau Matthew Rutler!

The pop star and her steady boyfriend were spotted on their way out the door to a Halloween bash, and the duo looked like they might have been doing a little pre-partying at her Beverly Hills mansion beforehand. Hey, as long as her son Max was with a nanny or daddy Jordan Bratman, nothing wrong with that! But hopefully she doesn't try to steal his thunder with another sexy costume when they go trick or treating on Wednesday night!

Now THAT'S a Halloween costume!

Hilary Duff did her best to win best costume of the year on Friday when she arrived in full Day of the Dead-inspired makeup to a Halloween party in Beverly Hills.

The 25-year-old actress' outfit looked just as amazing, pairing the work of art with a cleaving-bearing black corset and long red skirt. She wasn't the only one with makeup as her hubby Mike Comrie donned some white face paint to go with his skeleton get up. Glad to see them able to enjoy themselves without having to worry about baby Luca!

The saga continues!

Karrueche Tran and her friends, including Chris Brown and Christina Milian, opted for a costume-free Friday night as they grouped up to grab a bite to eat at Wokcano in West Hollywood.

Reports surfaced that the one-time couple enjoyed a late dinner in a quiet section of the restaurant, which included a visit from Christina. It's been known that Karrueche still holds a flame for her former boyfriend despite his relationship with Rihanna, which will undoubtedly make things more complicated for the maligned trio. Let the drama begin!

Derek Hough and his sister Julianne joined Maria Menounos and other celebrities as they attended a huge Halloween bash in Beverly Hills Friday night. Love the costumes!

The trio, wearing their best costumes, also met up with the likes of Rosie Huntington-Whiteley, Alessandra Ambrosio and Julianne's boyfriend Ryan Seacrest at the star-studded event in the hills. If only we could get a peek at what Ryan was wearing!

Now that's one hot cat!

Fergie gave a sneak peek at what she might be wearing this Halloween when she tweeted a provocative photo in her sexy form-fitting leopard print costume on Friday. "Getting excited 4 #Halloween! HEEeeRE naughty kitty kitty, HEEeeRE naughty kitty kitty," the Black Eyed Peas frontwoman posted to her Twitter account.

The 37-year-old singer has been known for her daring outfits but she's certainly outdid herself this time and we're sure hubby Josh Duhamel would agree!

Leave it to these ladies to do it right!

Last night, Rosie Huntington Whiteley and Alessandra Ambrosio threw on their hottest Halloween outfits as they headed to a private bash in Beverly Hills.

Both models looked sizzling in their sexy attire on the way to the exclusive event, which also included celebrity guests Derek and Julianne Hough and Ryan Seacrest. Talk about star power!
