BURBANK, Calif. (AP) — Bristol Palin said she didn't think twice before waltzing into "Dancing with the Stars," though she's barely danced in her life.

In an appearance Friday on NBC's "Tonight Show with Jay Leno," the 19–year–old daughter of former Alaska Gov. Sarah Palin says she learned about the invitation through a text message and signed within a week to appear on the new season starting Sept. 20.

Leno asked if she had gone to her high school prom. Palin replied "No, I was pregnant!"

That pregnancy put her in the spotlight during her mother's campaign for vice president in 2008. She had son Tripp that year, and recently she called off her re–engagement to Levi Johnston.

Palin told Leno she and Johnston weren't meant to be, and she's focused on being a mom.
