Ashanti REVS Some Engines At NASCAR

Ashanti (who celebrates her 34th birthday tomorrow) revved a few engines after showing off her toned abs at the Charlotte Motor Speedway racetrack yesterday.

Shanti was tapped to sing the National Anthem for the Sprint Cup Series Bank of America 500 NASCAR race. But before she performed, she got silly posing it up on the track:

She got dolled up in a rag & bone top, Alice & Olivia skirt and Giuseppe Zanotti booties to hit the stage. Cute.
