The beneficiary, Molly Bloom, was run over by a Hummer stretch limousine and dragged nearly 40 feet on prom night. The accident left her without a leg. Bloom’s supporters organized an event called "Mollypalooza" to generate money for her medical expenses. One of Bloom’s friends, Dmitri Lee Natali is helping to put together Mollypalooza. He says of Biel’s collaboration with the event, "My mom happened to be able to contact [Jessica’s] parents, and they had heard about Molly's tragedy. They said 'Yeah, I bet she'll do that.'"

The auction takes place at the Rock Island Club in Denver on Tuesday. Jessica will not be present for the event as she is busy filming her upcoming film, Next. Biel said in an audio clip for the Mollypalooza website, "I intend to submit a very special auction item as my contribution to the evening." The actress will be giving away a lunch date to the highest bidder.
