Kelly Carlson, Melanie Griffith

If you've ever wondered who brought Nip/Tuck's wild Kimber into the world, you'll soon meet her — and she'll be played by Melanie Griffith.

The Working Girl actress will play Brandie, Kimber's beautiful and considerate mother, who visits her ex-pornstar daughter from Wisconsin, a show insider confirms exclusively to TVGuide.com. (Griffith couldn't be better cast in terms of looks — her resemblance to Kelly Carlson, who plays Kimber, is striking.)

Brandie will be joined by Les, her too-tan, on-again-off-again car-salesman boyfriend of six years. Les, played by Robin Thomas (Another World, Who's the Boss), ignites insta-hate from Christian (Julian McMahon). The breast-cancer-battling doc sees too much of his own abuse of women — especially Kimber — in Les's treatment of Brandie.

Griffith's arc begins in the FX drama's seventh and final season. No airdate has been set for it or Season 6.

Are you excited to see Griffith tucked into the cast?
