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."

You go, girl!
