Which Celeb Is Showing Off Boxers and Back Tatts?

Rocker reveals his choice of underwear and his inked up back while promoting his new album

Baby got crack!

This rocker, who once dated a famous socialite, was promoting his latest album on TV when he gave a revealing rear view.

Not only can we see the color of his Hanes undies, but we get a look at those tattoos all over his back.

Think you know who's showing his skivvies and ink?

It's Benji Madden, on set at Fuse TV in NYC, where he was joined by twin brother Joel Madden to promote Good Charlotte's latest album, Cardiology.

Remember when he used to date Paris Hilton?

Looks like there's no hard feelings between the two exes.

She retweeted Nicole Richie and Joel's Tweets encouraging fans to purchase the new album on iTunes yesterday. That's what super famous exes are for, right?
