10 Celebs who had their first sex at a very young age (With Pictures)

2. Kelly Osbourne

Well, what do you really expect from the Osbourne clan? With Ozzy and Sharon as parents…well, a kid probably has more freedom than is really healthy or necessary. As for Kelly, she was just 13 years old when she did it for the first time. She wasn’t even menstruating yet, but she gave herself all kinds of worries thinking about whether or not she was pregnant. Hah! She wasn’t though, and she must have learned from her past experiences because now she is a very put-together woman, or seems to be at least. We loved watching her look all kinds of fabulous on Fashion Police.
