Kelly Osbourne was faced with her first pregnancy scare when she was just 13, the unconventional socialite confessed in a recent interview with New! Magazine.

Kelly, the youngest daughter of rock legend Ozzy Osbourne and his longtime spouse Sharon, tells the publication that she lost her virginity while still in her pre-teens.

“I convinced myself I was pregnant when I was 13 and I hadn’t even got my period!”

Today, Kelly, 23, says she is making wiser decisions regarding her sexual health. Tell New! she is screened for STIs “three, maybe four times a year.”

“Most of the time I don’t even need to. I just go for peace of mind.”
