Video: Navratilova emerges an elegant dancing star among "Stars"

You haven't seen anything until you've witnessed Martina Navratilova slipping under Tony Dovolani's legs and sliding 10 feet across a dance floor. In a dress, no less.

The Spin smiled all the way through the foxtrot with her "Dancing with the Stars" partner two nights ago. She has won 59 Grand Slam titles, and owns 55 years in this world to boot. And she's doing what she wants. See that dance here:

Their song was "Is You Is or Is You Ain't My Baby" by Renee Olstead, a great young artist and a great match for Navratilova's true elegance and, as she calls it, "body control." With Chris Evert on hand to watch, the duo scored 20 points total, notching marks of 7, 6, and 7 from the respective judges.

Martina's best quotes from their rehearsal footage: "See these biceps—they're useless!" and "I haven't worn a dress in 20 years."

Here's a candid, entertaining interview that the pair did for the show:

The best quote there: "I figured I needed somebody strong that could throw me around."

YOUR TURN: What did you think of Navratilova's performance? Think she has a chance to take this title? It seems she can only improve on tennis players' dancing ways to date.

Editors' Note: We incorrectly identified the singer of the song "Is You Is or Is You Ain't My Baby" as Diana Krall, when the singer is actually Renee Olstead. We have made the correction above.
