To the world’s surprise, Benji Madden marriedCameron Diaz Monday night. The secret ceremony took place at Diaz’s Beverly Hills home and the guest list was packed with fellow stars including Drew Barrymore, Gwyneth Paltrow, and Reese Witherspoon. Nicole Richie and of course, Madden’s twin brother, Joel were also in attendance as their son Sparrow (5) was the ringbearer. The two are rumored to be dating since May, but the Good Charlotte guitarist (35) reportedly proposed to the actress (42) just days before Christmas. Seeing as marriage tattoos have become quite trendy, we wouldn’t be surprised if the already heavily tattooed Benji and his bride paid a visit to the tattoo parlor in the near future. Photos of the big day have yet to surface, leaving Diaz’s dress up to our imagination *sad face*. Congrats to the newlyweds!
