Imagine having not only one superstar in your Algebra class -- but two! Yep, some high schools are lucky enough to be graced with two future celeb students at the same time.

We couldn't believe it either, so we did some research and found a surprising number of stars who were classmates. While some of the celebs went on to find success in the same field (like Jessie J, Adele and Leona Lewis), others went on to thrive in completely different areas (like Cameron Diaz and Snoop Dogg!).

Still don't believe that that much star power was packed into the same schools? Check out the gallery above to see which celebs attended high school together!
