What does Britney Spears need in her ideal guy?

Seems the criteria for Britney Spears' ideal guy is really high.

All the 34-year-old songstress needs is a mix between Bill Gates and rapper The Game, reports TMZ.com.

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

The 'Crazy' crooner got real specific, saying she needs a 'hot nerd'.

Now that was innocent yet straight-forward enough.
