Washington, July 27 : Former Miss California Carrie Prejean, who was controversially dethroned, surprised most when she performed a live song to celebrate the 70th anniversary of the Del Mar Racetrack on July 22.

Prejean, 22, was seen joining Audrina Patridge and Wilmer Valderama at the event that took place in San Diego, reports Fox News.

The former beauty queen sang the classic "Where the Turf Meets the Surf", a jingle that Bing Crosby wrote for the horseracing track in 1937.

Earlier Prejean, who had caused a public outcry in April when she spoke out against same-sex marriage at the Miss USA contest, announced that she was writing a tell-all, entitled "Still Standing", to spotlight her victimization by the liberal media. (ANI)
