In an unusual, exciting piece of casting news, a star of V is crossing over to CBS.

Morena Baccarin - who portrays the leader of the Visitors on that ABC drama - will guest star on an upcoming episode of The Mentalist.

According to Entertainment Weekly, the actress will portray Erica Flynn, described by CBS insiders as “attractive and sexy woman who seems as warm-hearted, sincere, and intelligent as she is lovely.”
