Reese Witherspoon: Livestrong Foundation Support!

Reese Witherspoon is all smiles at The Livestrong Foundation’s “Art Mere Art Pere Night” at Smashbox Studios on Thursday (September 23) in Hollywood.

The 34-year-old actress joined others to help support Livestrong, the organization Lance Armstrong established to support fellow cancer survivors and their families, which offers a multitude of resources to help pediatric cancer survivors and their families manage the long-term effects of childhood cancers.

Guests sipped on Corzo cocktails and munched on Fatburgers at the chic event for a good cause, which was hosted by Reese‘s beau, Jim Toth!
