Let's hope the marriage lasts, because this tat definitely will!

Benji Madden and Cameron Diaz are still in the honeymoon phase and head over heels for each other, and the Good Charlotte singer decided to prove his undying affection for his new wife Cameron Diaz by getting her name inked on his chest!

The rocker is already covered in tattoos, so this isn't quite as dumb an idea as when clean cut Nick Cannon tattoed Mariah's name on his back, but it's definitely something that will need to be covered with a giant tiger or something if they ever break up!
