Treating herself to a girls' night out, Christina Aguilera was spotted grabbing up a fancy dinner in Los Angeles, California on Friday evening (August 13).

Dressed up in blue dress with a black leather jacket, the "Burlesque" beauty hopped out of her Range Rover backseat perch to head inside BOA Steakhouse with her lady friends.

The BOA night comes shortly after it was announced that Miss Aguilera is set to perform at a fundraiser to bring in cash for the Los Angeles County Museum Of Art's latest project.

The 29-year-old Grammy award-winning songstress will be taking the stage on September 25th at the grand opening celebration of the museum's Lynda And Stewart Resnick Pavilion.
