Which Musician Is Rocking Tiger-Striped Hair?

Rocker sports edgy new yellow and black striped 'do on Twitter—but who is it?

When being a rock star isn't enough, some celebs cross over to the wild side.

One musician went so far as to transform his regular brown hair into a tiger-striped 'do.

"I prayed for a tiger in the bedroom & this is what I got," his wife quipped, posting a pic of her man's yellow and black striped hair to Facebook.

So who's the fashion star making such a statement with his hair?

It's Joel Madden!

The Good Charlotte singer debuted his new locks just shortly after wife Nicole Richie dyed the ends of her tresses hot pink.

Gotta love Nicole and Joel's romance: They live and dye together!
