Britney Spears I Need A Nerd With A Giant Penis?

Britney Spears' ideal guy is a mix between Bill Gates and rapper The Game.

Spears was performing at her Vegas residency Sunday night, but went a little off script when it came time to pick out a random guy from the crowd.

Brit got real specific, saying she needs a "hot nerd" -- innocent enough -- but it sounds a lot like she wants one who's packing in the right places.

Makes you wonder how many guys raised their hands. Probably not many at first ... and then way too many to be true.
