Every high school has its archetypes and cliques. The jocks. The cheerleaders. The stoners. The mathletes. The nerds. The ragers. The theater and art kids. Some are peeps you remember well. Others fade into the halls of your memory. Lady Gaga and Nicky Hilton can never forget one another. Neither can Adele and Jessie J, since they attended the same high school!

Did you know that two extremely successful rappers walked the halls of the same Brooklyn learning institution? Plus, a famous actress who has been named Esquire's Sexiest Woman Alive dated her classmate, a future rocker.
