Renée's Late-Night Dish

Renée Zellweger stopped by "The Late Show with David Letterman" and she played with her food, instead of dishing about beau Bradley Cooper.

The Oscar-winning actress talked about her new business venture, Blue Parrot, the Mexican restaurant she opened in East Hampton, NY. "Being a Texan, I'm very, very critical about the guacamole everywhere," Renee said.

Letterman brought out a piñata full of guacamole. Zellweger, in a blue strapless dress, grabbed a bat and she and Dave whacked the stuffed donkey until it crashed to the floor.

Then they tasted the guac and she joked, "Where are the chips?"

Renée's film, "My One and Only," hits theatres today.
