HOLLYWOOD, Calif. — Britney Spears slipped into her bikini Tuesday night for a taped appearance on the "Late Show with David Letterman."

The 27-year-old pop star wore a black bathing suit with a red hibiscus in her hair as she read the "Top 10 Ways the Country Would be Different if Britney Spears Were President."

"I'd be the first president to wear eye shadow since Nixon," she notes in one difference. Also on the list are "we would only invade fun places like Cabo" and "free pie for everybody."

And the No. 1 item on the list: "Finally the media would pay some attention to me."

This visit marked the singer's first appearance on the show since a surprise cameo appearance on Nov. 6, 2006.

Spears recently finished the European leg of her "Circus" tour. She'll kick off another batch of concert dates in North America on Aug. 20.
