Diaz and the shorter more tattooed Madden twin got married in a ceremony at their shared Beverly Hills mansion on Monday evening after dating for just eight months.
Attending the ceremony were A listers such as Drew Barrymore, Gwyneth Paltrow, Reese Witherspoon and Diaz's new sister-in-law, Nicole Richie, with her husband and Benji's twin, Joel Madden.
Boyfriend and affair Diaz dated the actor Matt Dillon, for three years until 1998.
She was also once engaged to Jared Leto, but they broke up in 2002.
When I first reported that Cameron Diaz was dating Benji Madden back in May, the only comment I received was an accusation the unlikely couple must have been photoshopped together in the images.
Now the pair are bound together in holy union FOREVER.
Women are caretakers by nature, don't take it for granted.
