Is it true that Nicole Richie had like over 20 boyfriends (I saw that on some website I googled)?

It doesn't really matter much now since she's with Joel Madden & has a baby for him. I'm just curious. & I also heard she dated the singer, Aaliyah's brother Rashad. Not sure if it's true or not. Aaliyah was the one who died in the plane crash shortly before 9/11.
