The I Think We're Alone Now singer, who once posed for Playboy, admits she let herself go in recent years, and "ballooned" to 152 pounds (68.9 kilograms) - 25 pounds (11.3 kilograms) over her ideal weight.

The single mum, 35, says, "Emotionally, when you're not feeling so great, you think, 'What the heck, I'm gonna have the chocolate cake.'"

Her slim down on Celebrity Fit Club helped the singer shed 30 pounds (13.6 kilograms) and now she's thinking about a return to Playboy: "I would say yes to Playboy again. It boosted my self confidence."
