Benji Madden‘s got a head full of ink.

The Good Charlotte rocker, 36, debuted his new intense (and massive) head tattoo when he stepped out with wife Cameron Diaz on Saturday night.

Madden sported his new tat as he and Diaz left West Hollywood hot-spot (a favorite of the Kardashian-Jenner family) The Nice Guy.

The intricate ink, which features diamond shaped patterns and a skull, covers most of the musician’s shaved noggin. There’s a possibility that the design could just be temporary, but the musician is no stranger to getting inked. Madden already has a slew of tattoos, including Diaz’s name – which he added across his chest in February.

The 43-year-old movie star looked polished in a patterned white and purple knee-length dress and nude pumps.

Are Cameron Diaz and Benji Madden Getting Ready for a Baby?

Diaz and Madden got married in January after a brief engagement. The couple first began dating last in May 2014.

A source close to the actress previously told PEOPLE that the pair is already “eager to have children.”

“[Cameron] will take things as they come, but don’t be surprised to see her calm down a bit and get in the best shape for a possible pregnancy,” the source said.
