Nicole Scherzinger is proving that she's got the X Factor when it comes to her job and that insane bod! But the former Pussycat Doll singer has been working on her body since age 14.
The 33-year-old X Factor judge tells Shape:
"I started jogging and counting calories when I was just 14. I've been on every diet you can imagine. By the time I was in the Pussycat Dolls, I was on the scale all the time. It became my enemy because I noticed that when I exercised really hard, I'd gain weight."
When it comes to food, Hawaiian-born Scherzinger admits, "Actually, I eat - a lot!" Her motto is: "Stay active, eat everything in moderation, and stop being so tough on myself."
The new X Factor judge went on Conan last night in a very tight leopard print dress that left very little to the imagination ... especially when it came to her cleavage.
Conan O'Brien tries to concentrate during the interview, but his eyes begin to drift downwards when she starts talking about why all the ladies love Simon Cowell. So she says, "Focus, Conan," and directs him back up to her face. "I'm trying to speak here," she laughs. "Serious talk."
How does Conan respond? "It's so [unfair]. I'm sorry! ... Good god! Finally let's be real here for a second. You didn't think I was gonna look down there?" And then he proceeds to mock-motorboat her.
