Kim Kardashian's Baby Bump Growing Bigger (PHOTO)

Pregnant Kim Kardashian made her way through to the opening of the Tracy Anderson Flagship Studio on Thursday night in Brentwood, Calif.

The 32-year-old reality star and girlfriend of Kanye West wore (surprise!) leather leggings and a silky top that showed off her swelling baby bump and chatted with the likes of Molly Sims as they helped inaugurate the celebrity personal trainer's new studio. Gwyneth Paltrow also strutted the red carpet but was not photographed with Kim.

Anderson -- who recently helped Kardashian sister Kourtney lose 44 pounds in six months -- has been working to help keep Kim fit throughout her pregnancy.

"We take it one day at a time," Anderson told Us Weekly in January. "One of the things that I love is that she doesn't want to go crazy. She's not interested in being like, 'I want to look hot during my pregnancy' or anything like that. Just like, 'I want to be healthy, I want to take care of myself and the baby...' She knows I'll get her back better than ever after [the birth]."
