She then showed off her famously slim figure on Sept. 8 in London – just two months after giving birth! 03 of 07 JESSICA ALBA Splash News Online; Fame Admitting that she "never felt less sexy" than when she was pregnant, Alba wasted no time after the June 7 birth of daughter Honor Marie. Thanks to hour-long workouts, five or six days a week – plus a strict diet of 1,700 calories a day, according to trainer Ramona Braganza – the actress (at the ALMA Awards) dropped 25 lbs. in three months. 04 of 07 NICOLE RICHIE Vince Flores/Celebrity Photo; Donato Sardella/WireImage "I felt great physically," Richie told PEOPLE of gaining pregnancy weight. "It wasn't something I thought about. It was more like, 'What am I going to wear?' When I stopped fitting into my jeans, I wore leggings." And after Harlow Winter's birth Jan. 11, her body bounced back naturally. "People asked me if I work out. I'm like, 'I don't know what kind of time you think I have!'" 05 of 07 GWEN STEFANI Flynet; Stefanie Keenan/Patrick McMullan/Sipa The singer – who admitted to Harper's Bazaar that her weight is "an ongoing battle and it's a nightmare" – looked lean and chic less than two months after the Aug. 21 birth of her second son, Zuma Nesta Rock. "It's so much work [after pregnancy] to get the weight off," she has said. "If you just do it, it comes off." 06 of 07 CHRISTINA AGUILERA Mullen-Rilloraza/JFX; Kevin Mazur/WireImage "I never felt my weight get out of hand," the singer said about carrying son Max Liron, born Jan. 12. So she waited until mid-March to exercise with trainer Tee Sorge. "I do the treadmill, I box, and I do a lot of weights. I feel so much better when I work out." She also burns calories breast-feeding – and by summer, Aguilera was back in body-hugging dresses. 07 of 07 JENNIFER LOPEZ Splash News Online; Fame She gained 50 lbs. during pregnancy, but Lopez didn't let that get in the way of a glam night in New York, just weeks before the Feb. 22 birth of twins Max and Emme. She took it easy for four months – then started working out six times a week with Gunnar Peterson, who trained her for a charity triathalon in September.
