Drew Barrymore gets married with BFF Cameron Diaz at her side!

Drew Barrymore is officially married! The 37-year-old actress and now-husband, art dealer Will Kopelman, were wed in front of an intimate group of family and friends on Saturday at Barrymore's California estate. One of the many famous faces in attendance? Latina actress and Barrymore's BFF, Cameron Diaz!

Diaz, who was reportedly a bridesmaid at the wedding, has been a helpful and comforting presence to Barrymore throughout the planning process--particularly since the new bride is pregnant with her and her new husbands first child! In fact, Diaz recently told the July issue of Instyle UK that Kopelman sought her advice before popping the question.

"My girlfriends are like my soul sisters," said Diaz. "I knew Drew was getting married before she did."

Aww! What an amazing and supportive friend! Below, some more of Diaz's top BFF moments:
