PIC: Jenny McCarthy's Diet Secrets, Workout Routine

One of the most popular models and MTV VJs of the 1990’s, Jenny McCarthy, 40, is celebrating her birthday by appearing on the cover of Shape magazine. Lifting up her shirt, McCarthy reveals a well-toned, washboard stomach.

“This is my second time doing Shape, and I feel really kind of honored,” McCarthy told E! News. “If they ask me to be on the cover, that means I’m doing something right,” she added. McCarthy was last on the cover in 2009.

Showing off her body in two-piece bikinis, McCarthy also reveals her dedication to exercise, even within a short time frame. “If I only have 10 minutes, I definitely have a go-to workout, and that is to lunges, sit-ups and pushups,” McCarthy says.

McCarthy also discussed her diet. “My go-to healthy snack, without a doubt, and it works so well, is watermelon. It fills you up,” she says.
