Nicole Scherzinger has invited U.S. vice presidential candidate Sarah Palin to join the sexy girl group, if her election campaign fails next month.

The singer is convinced former beauty queen Palin has got what it takes to join the all-singing all-dancing five-piece.

Scherzinger says, "She seems like a headstrong woman, a tough chick. And she's hot."

It's not the only offer on the table for the 44-year-old Republican governor of Alaska - Playboy boss Hugh Hefner has already asked her to strip naked in the famous men's magazine.
