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.

Find out what celebrities were classmates and are alums of the same high school.

  • Jay Z and Busta Rhymes

    Rap reigned supreme in the 718! Jay Z and Busta Rhymes roamed the halls at the George Westinghouse Vocational and Technical High School in Brooklyn, N.Y. Notorious B.I.G. was also a student at the same time. The Hova went from selling crack to owning his own sports agency. Busta, known for his braids, served up plenty of hits. And we all know how Biggie, who transferred to this state-funded school, ended up -- gunned down as part of the East Coast vs. West Coast rap wars.

  • Lady Gaga and Nicky Hilton

    To quote the Red Hot Chili Peppers, Catholic school girls rule! Back when she was Stefani Joanne Angelina Germanotta, Lady Gaga was rubbing elbows with hotel heiress Nicky Hilton at Convent of the Sacred Heart in New York City. Gaga spoke about attending school with Nicky and her older sis Paris, saying, "They're very pretty, and very clean. Very, very clean. You know, I never saw Paris, she was older than me, and it's funny that the press always write that I went to school with the Hilton sisters, but I actually only went with Nicky." Very clean, huh? Well, cleanliness is next to godliness, and it was a Catholic institution, so…

  • Tupac Shakur and Jada Pinkett Smith

    The rapper and the actress attended the Baltimore School for the Arts in Maryland at the same time and were quite close. They made a video together at the King's Dominion amusement park in Virginia, where they lip-synced to her future husband Will Smith's hit single 'Parents Just Don't Understand.' It was a harbinger of her future. Sadly, he was gunned down in the same rap war as Biggie.

  • Cameron Diaz and Snoop Dogg

    Long Beach Polytechnic High School in sunny So. Cal was the academic institution of both rapper Snoop Dogg -- when he was Calvin Broadus -- and actress Cameron Diaz. "We went to high school together," Diaz revealed on a talk show. "He was a year older than me... I remember him, he was very tall and skinny. He wore lots of ponytails." We wonder if he was sparking spliffs at the time, too! Just sayin'.

  • Lauryn Hill and Zach Braff

    New Jersey is a breeding ground for talent, as singer Lauryn Hill and 'Scrubs' star Zach Braff both attended Columbia High School in Maplewood, a suburb in the northern part of the state. They were friends and she was even invited to attend the actor's bar mitzvah, so they knew each other for quite a while. Braff had gone on 'The Howard Stern Show' and said that the Hill of then was much different than the Hill of now. You know, the Hill of now is the one who just got out of jail for tax evasion.

  • Jessie J, Adele and Leona Lewis

    That's a lot of vocal talent right there. Beautiful Brits Adele, Jessie J and Leona Lewis all attended the BRIT School in Croydon. Double J and Adele used to have lunch together, so they go way, way, way, way back! They even sang together. Jessie J said, "I knew Adele; we were in the same year. We used to hang out at lunchtimes and have a little jam. We’d sing songs we’d written or perform whatever we were working on. When Adele started to take off -- BRIT old girl Amy Winehouse was already huge by then -- it was amazing to have the opportunity to watch and learn."

    Brit singers Florence Welch and Jessie Ware both attended Alleyn's School, an independent, co-educational day school, in their native England, as did many other famous peeps, like Jude Law.
