Looks like rocker girlfriend Avril Lavigne has Brody Jenner doing all sorts of new grooming and "enhancing."

After tattooing Lavigne's name on his arm, now he's sporting a new shorn 'do.

"The Hills" star showed up at L.A. restaurant Katsuya with a mohawk a few days ago, much to everyone's surprise.

Was he channeling famous celebrity mohawks of days past like David Beckham, Rihanna, or Maddox Jolie Pitt? Or just trying to fit into his new rock 'n roll scene?

We'll have to wait and see.

In the meantime, see what other celebrities are doing questionable things with their 'dos.
