She’s made quite a name for herself thanks to her penchant for partying and nutty antics, but Nicole “Snooki” Polizzi actually comes from a pretty dark past.

During “Dancing with the Stars” last night (October 7), the “Jersey Shore” starlet confessed to a serious eating disorder during her high school years.

Snooki shared, "Cheerleading was my life in high school but it wasn't always easy for me. I started to be anorexic. There were these little girls coming up, like freshmen, who were literally, like, 70 pounds."

"And I was like, my spot as a flier is going to get taken away. So I ended up starving myself. I started eating one salad a day, and then it became, like, one cracker a day, and then it became just one grape a day. And then… just not eating at all for three days. It was a really, really, bad time for me."

Polizzi added, "I definitely thought I should bring it up on this show because a lot of kids watch, and I just wanted kids to know they can overcome it. I think a lot of high school kids go through that, I think every girl struggles with that at some point, so it's important."
