Audrina Patridge: Pretty at the Pepsi 500

She’s a well-known fan of racing, and yesterday (October 11) Audrina Patridge satisfied her need for speed at the NASCAR Sprint Cup Series Pepsi 500.

The Hills babe looked lovely as she meandered around the Auto Club Speedway in Fontana, California, posing with the green flag prior to the start of the race.

And of course, Miss Patridge looked way hot, sporting a grey form-fitting top teamed with a pair of black leather trousers and black boots.

On Friday night (October 9) Audrina was busy supporting the Surfrider Foundation at its 25th Anniversary Gala at the California Science Center’s Wallis Annenberg Building. What a busy weekend!
