Hot mama!

Former Bachelorette Jen Schefft and hubby Joe Waterman welcomed their first child, daughter Mae, in November 2010.

The 35-year-old admitted she eased up on working out during pregnancy, but post-baby, she was ready for her old body back! "Maybe it took me about three months to get back in the gym," she told Us Weekly at a photo shoot showcasing her svelte figure. "You just don't realize how out of shape you really are."

Once Mae was six months old, Schefft began to feel "like my old self again."

So how'd the reality star drop 40 pounds of baby weight and fit back into a size 4? Bikram yoga, as suggested by her hubby, and a diet defined by moderation rather than restriction.

"I feel good about my body," she told Us. "I'm not exactly where I wanna be. Things don't look exactly how they used to, but I am happy."
