Some celebrities knew each other BEFORE they were famous . . . like back when they were KIDS.

 

Here are some examples:

 

Gwyneth Paltrow and Maya Rudolph.  They were classmates at St. Augustine by the Sea school in Santa Monica.

 

Jennifer Aniston and Chaz Bono.  Back when Chaz was a girl named Chastity, she and Jennifer were buddies at New York's High School of Performing Arts.

 

Kim Kardashian and Paris Hilton.  They'd been friends since preschool, and remained so into their 20s.  But with the release of Kim's sex tape in 2007, she started eclipsing Paris as America's favorite "celebutante".

 

Paris wasn't cool with that . . . and the following year she effectively ended their friendship by saying that Kim's ass looked like, quote, "cottage cheese inside a big trash bag."  They made up, but the friendship never really recovered.

 

Selena Gomez and Demi Lovato.  Okay, so you probably DID know they were childhood friends.  They met on the set of"Barney and Friends".

 

Cameron Diaz and Snoop Dogg.  They went to Long Beach Polytechnic High School together.  Snoop has even suggested he was her dealer . . . quote, "I might have sold her some of that white girl weed.  You know, sticks and stems and seeds."

 

Courtney Love and Drew Barrymore.  They met when Drew was 8 and Courtney was 18 or 19.  Courtney says Drew was, quote, "in a bathroom, smoking" when she met her for the first time.

 

Naomi Watts and Nicole Kidman.  They met at North Sydney Girls' High School in Australia.  Nicole was actually born in Hawaii, but her parents are Australian.  And they moved back there when she was 4.

 

Tyra Banks and Kimora Lee Simmons.  They met as teenagers modeling for Chanel.
