After three kids, it would seem Poppy Montgomery's post-baby slim-down routine would be like second nature. But she reveals it's a lot harder than it looks -- and there's always some new weight-loss trick to try out!

"I bought this really good jacket that's hiding everything right now," Poppy joked to at the Marvel Universe Live event in Inglewood, Calif. on May 2, 2015, when asked her secret to looking fit after giving birth nearly six months ago. "It's all wardrobe."

The 42-year-old "Unforgettable" star welcomed her third child, a son she and husband Shawn Sanford, a Microsoft exec, named Gus, in November of 2014. Gus is Poppy's second child with Shawn. They are also parents to daughter Violet, while Montgomery has a 6-year-old son, Jackson, with ex-husband Adam Kaufman, and Sanford has a son and daughter from a previous marriage.

To lose those pounds she gained while pregnant, Poppy says, "I have to work out. I've had two kids in two years. It's really hard to get back into shape, especially to get camera ready. My show starts filming again May 11th for the fourth season. It's never easy. I work out, diet, drink water and try not to binge in the middle of the night, which I do constantly. I totally derail."

While nursing in the wee hours of the night, she adds, "I'll wake up and be like, 'Ooh cookies.'" But she tries not to let cravings for things like sweets, pasta and McDonald's take over. "Grilled fish and vegetables is what I should be eating. My secret is to try to have more good moments than bad moments."

To combat the hunger pains, Poppy works out about five to six times a week. "I do an hour with my trainer or I spin," she says. "I go to Soul Cycle or I go to yoga. I've got so many children that fitting it in becomes hard so I do what I can."

Does she have a method for balancing it all? "Oh we don't," she admits. "We're out of our heads all of the time. There is no balance. It's like a circus. It's pretty wild, but it's fun."
