Callie Thorne is coming to Californication.
The actress, who starred for years on Rescue Me as Sheila Keefe, will guest star on season four as a single mother that gets involved with Hank.
But here's the twist, as reported by Fancast.com: Thorne's character will be the mother of the actress who is portraying Hank's daughter in the movie being made about his life. Moreover, Hank is sleeping with that actress (played by actual actress Addison Timlin).
Read that again. I promise it makes sense.
Rob Lowe will also play a key role on season four of the show.
