"A Piece of Me" singer Britney Spears, apparently wants a piece of a "hot nerd" and his "big p*nis!" Check out with BritBrit told fans during her Las Vegas show the other day: "I think it’s time to find a hot nerd, like, a really hot guy, with a really big p*nis ... Men, frankly, can suck my f---ing toe."

Uh, Britney, TMI! Still, from what we hear, this was the most interesting part of the show. We're getting reports that there's LOTS of lip-synching and LOTS of unenthusiastic dance moves. Say it ain't so!

Maybe Spears should go to the Miranda Kerr school of dating -- Evan Spiegel's a hot, 25-year-old nerd and, well ... we don't know about the other part :)
