Gwyneth Paltrow: Tracy Anderson Studio Opening!

Gwyneth Paltrow and her pal Tracy Anderson celebrate the opening of the Tracy Anderson Flagship Studio on Thursday (April 4) in Brentwood, Calif.

The 40-year-old actress looked great in a Victoria Beckham dress and Michael Kors shoes.

Gwyneth and Tracy were joined at the opening by a pregnant Kim Kardashian, Molly Sims, and Stacy Keibler.

That same day, Gwyneth‘s husband Chris Martin, 36, was spotted taking their kids Apple, 8, and Moses, 6, to the Santa Monica Pier, where they were seen leaving with a ton of stuffed animal prizes!

FYI: Stacy is wearing a Rebecca Minkoff dress and Giuseppe Zanotti shoes. Molly is wearing a Rebecca Minkoff jacket.
