Emily Maynard is revving up her dating life!

Just three weeks after officially splitting from her "Bachelorette" fiance of five months, Jef Holm, the reality star was spotted getting cozy with a new man: Nascar truck racer Jason White, 33, observers tell Us Weekly exclusively.

"They were all over each other," says a witness who saw the single mom, 26, and the Richmond, Va.-bred driver on a group date at the Nov. 3 Carrie Underwood concert in Charlotte, N.C. "Jason guided her through the crowd and held her hand as they walked downstairs." (They later ventured off alone to the club Suite, a source tells Us).

White is, of course, not the first racer she's romanced.

The late Ricky Hendrick, her first fiance and dad of her daughter, Ricki, 7, was a Nascar driver, and she was linked with Dale Earnhardt Jr., 38, in 2006.

"Emily tried something new, dating Jef," says a pal. "She is going to go back to what she knows and considers safe."
