Mercedes Masöhn to Guest Star on Californication

Mercedes Masöhn is on her way to Californication.

The actress - last seen on 666 Park Avenue - will guest star on Season 7 of the Showtime hit a TV star named Amy Taylor Walsh. Look for her to be in need of Hank’s help in some way when the series returns next year.

Masöhn is the latest big name to join the comedy.

Michael Imperioli will stop by as a television producer who plays a key role in Hank's latest project, while Heather Graham will recur throughout the season as an ex-flame and Mary Lynn Rajskub will appear on three episodes as a writer.
