It appears that Jorja Fox’s on-again, off-again relationship with the long-running CBS hit “CSI” is on again. And this time it’s permanent … for now.

The actress who plays crime scene investigator Sara Sidle has signed on as a series regular after four seasons as a guest star, according to a report from TV Line.

Fox has disappeared and re-appeared from the show seemingly as many times as the Miniature Killer that almost took the life of Fox’s character. She first was fired from the show after a contract dispute in 2004, only to be rehired shortly thereafter.

Only time will tell.” She then returned for a stint in 2008 and continued her guest starring role through the end of last season.

Fox’s re-hiring comes just days after show execs announced that the Ted Danson would be taking over the lead of “CSI,” filling the hole left with Laurence Fishburne’s departure.
