"Sin City" star Jessica Alba sinks her teeth into her sweetest role yet this weekend -- she is a special celebrity guest on the season 9 premiere of the Food Network competition show "Cupcake Wars."
The 32-year-old actress and mother of two serves as a guest judge on the episode, which airs on Saturday, Sept. 7 at 8 p.m. ET.
The contestants compete to try to bake the best all-natural, organic cupcakes for her and the other judges. The winner gets $10,000 and the chance to cater a launch party for Alba's new family brand, The Honest Company, which offers eco-friendly baby, bath, health and wellness products.
"As a guest judge and foodie, I was blown away by the contestants' culinary creativity in baking cupcakes that were made with healthier ingredients but still tasted and looked amazing," Alba says in a statement posted on the official blog of "Cupcake Wars."
