Cheers! CSI is about to host a quasi reunion for Ted Danson and Peri Gilpin.

The actress - who appeared opposite Danson on an episode of Cheers and then later on another episode of Frasier - will come on board the CBS drama later this season as Alison, D.B. Russell's wife.

The character will debut on the May 9 CSI season finale and then return next season for multiple episodes. She's described in network casting notes as the "intellectual equal of her brilliant husband, the one woman who doesn’t just rule his heart, but rules his life.”
