Kim Kardashian is starting to show off her post-baby curves, and wore a form-fitting green jumpsuit while filming her E! reality show this week. Wearing beige heels, the reality TV star left a few buttons on the top of her jumpsuit undone, revealing the cleavage that she has been hiding since giving birth to North West in June. Her famous derriere was also on display.

She and her new best friend, Blac Chyna, a former stripper and current girlfriend of rapper Tyga, had lunch with Kourtney Kardashian and Scott Disick at Stanley’s restaurant as a camera crew followed them.

By the looks of it, the 32-year-old is quickly losing the weight she gained while pregnant after being widely criticized for the pounds she put on during her pregnancy.

Though it is unclear how much more weight she has to lose, Kardashian has been working with celebrity trainer Tracy Anderson, who has whipped into shape stars such as Gwyneth Paltrow and Nicole Richie.

Anderson told E! recently, “She's a gorgeous woman. I think the reason why the weight is coming off is because she's very connected. I went and met little North,, and Kim's really taking it in stride. She's really connected to the baby, which is what's important. She's focused on the baby and nursing and taking her time.”
