Benji Madden Debuts Crazy Massive Skull Tattoo During Night Out With Cameron Diaz

A skull on his skull.

Benji Madden is a man of many tattoos, and now he has one more that really makes us wonder just how high his pain tolerance is. 

On Saturday, the 36-year-old "Good Charlotte" guitarist debuted a massive tattoo of a skull along with some intricate designs on -- where else but -- the top and back of his own skull. 

Madden was spotted rocking the new ink while leaving The Nice Guy in Los Angeles with wife Cameron Diaz. 

No word on how many tattoos Madden has at this point, but he got Diaz's first name tattooed on his chest in February and also has a huge tattoo of Benjamin Franklin on his back.
