Mohawk, tattoos — all signs of a serious punk rocker, or in the case of Brody Jenner, being in love with a punk-pop princess. Jenner and his girlfriend Avril Lavigne hit the streets of L.A. with the former Hills star sporting a new addition to his fresh new haircut, a “A”, presumably in honor of the singer’s first name. We can’t be too surprised with Jenner’s locks showing his loyalty to his lady-love, after already inking his arm with her name back in July. And unlike a permanent tattoo, at least hair grows back in relatively painlessly. Tell us: What do you think of Brody shaving Avril’s initial into his hair?
