Jessica Simpson Isn't Shamu Shy

Jessica Simpson pumps up the jams while performing at Sea World in San Antonio, Texas on Saturday (May 9) as part of the park’s “Bud & BBQ” country-music series.

During rehearsals, the 28-year-old country singer wore a navy blue dress but then stripped down to a pair of ‘Daisy Dukes’ cut-off denim shorts for the real deal.

“Going on stage now,” Jess tweeted before her performance. “Get ready for greatness, Shamu.”

After her performance, Ms. Simpson blogged, “Just overcame my fear of sharks by kissing a killer whale.” Pictured below!
