That's one way to show someone how much you care!
Hills alum Brody Jenner -- who debuted a mohawk just last week -- was spotted in L.A. Saturday with the letter 'A' shaved into the right side of his head.
Perhaps the 26-year-old did it for his rocker girlfriend Avril Lavigne, who he's been dating since the spring.
This isn't the first time Brody has altered his appearance to prove his love for Lavigne. In early July, he reportedly got a tattoo of the 25-year-old singer's name on his left forearm.
So what does Brody's dad Bruce Jenner think of his son's new rocker look?
"It seems like in today's society, getting tattoos and piercings, changing the hairstyles, going pink and purple and all that, it seems to be their generation," Bruce, 60, tells UsMagazine.com. "But hair can grow back! He'll be fine."
