Christina Aguilera and boyfriend Matt Rutler made their way into The Roxy last night to catch friend Linda Perry in concert. Nice Michael Jackson tank, Xtina!

The couple, both wearing hats, seemed excited to see Perry and her band Deep Dark Robot perform at the Hollywood hotspot.

Xtina and Perry have worked together in the past. The former 4 Non Blondes singer wrote several of Christina's biggest hits including "Hurt," "Candyman," "Keeps Gettin' Better" and "Beautiful."

The 30-year-old Burlesque star was recently honored in West Hollywood. Find out why ... after the jump.
