An actress and model appearing on several "100 Sexiest Women" lists over the years, Cameron Richardson entered the spotlight with her role as Claire in the 2007 family comedy "Alvin and the Chipmunks." But Richardson was hard at work modeling and acting before her big break: she posed for magazines such as Mademoiselle, Cosmopolitan, and Ocean Drive, and performed supporting roles in the docudrama series "Cover Me," "Entourage," and the medical drama "House." She has also found consistent work in commercials, including spots for Corona and Carl's Jr., with the latter featuring Richardson on a mechanical bull with a burger in hand.
