Beautiful actress Eva Longoria Parker served up hamburgers and milkshakes to several pleasantly surprised customers Tuesday at a Wendy’s in her hometown of Corpus Christi, Texas in order to promote the fast-food chain’s forthcoming Father’s day Frosty Weekend, E! online reports.

The “Desperate Housewives’” star surprised customers at Wendy’s, where she used to work as a teenager. Eva was employed by Wendy’s for three years, from 1991 to 1994.

A customer at the Corpus Christi franchise said: “It was quite surreal to see a Hollywood star behind the counter but she was really friendly and fitted right in.”

The event donates 50 cents to the Dave Thomas Foundation for Adoption and Wendy’s Wonderful Kids for every frosty sold.

It was recently reported that Longoria is “desperate” to have a baby with husband Tony Parker. “Tony isn’t ready for a baby. He’s much younger than Eva and at the top of his profession, while Eva is in her ‘baby prim’ as she calls it. She even threatened to leave him twice before he agreed,” a source close to the couple said.

33-year-old Longoria has model contracts with L’Oreal, Hanes and New York & Co. She became famous while starring as Gabrielle Solis in the ABC television series “Desperate Housewives.”

Longoria also became a nationally recognized model after appearing in many advertising campaigns and several men’s magazines. She married NBA guard Tony Parker in 2007 and recently declared she is ready to quit “Desperate Housewives” in order to start a family. However, the stars from the hit TV series renewed their contracts with ABC for other four years.
