Britney Spears unleashes her inner-fangirl after meeting AJ McLean

Britney Spears unleashed her inner teen fangirl when Backstreet Boy AJ McLean stopped by to see her Las Vegas show.

Britney posed with the singer for pictures, before telling Twitter followers that she is the "biggest" Backstreet Boys fan.

Britney probably didn't get to spend too much ​time with the Backstreet Boys back when she was dating Justin Timberlake from rival group NSYNC.

Britney Spears has been busy in the studio with her manager. Her new album is "80% done" and apparently it "sounds amazing".
