Cameron Diaz is officially off the market after tying the knot with rock star Benji Madden at their Beverly Hills mansion on Monday evening.

The Annie actress, 42, and former Good Charlotte star Benji, 35, wed following an eight month courtship.

'We couldn't be happier to begin our new journey together surrounded by our closest family and friends,' the couple said in a statement to People.  

In attendance were Reese Witherspoon, Drew Barrymore and Gwyneth Paltrow as well as Diaz's new brother-in-law, Benji's twin Joel and his wife Nicole Richie.

Samantha Ronson, Toni Collette, Jeffrey Katzenberg, producer Nancy Juvonen and Pussycat Dolls choreographer Robin Antin were also in attendance.

Joel and Nicole's son Sparrow, five, served as the ring bearer. The bridesmaids were Richie, Barrymore, Cameron's sister Chimene and her assistant Jesse Lutz, according to UsWeekly.
