Sharon Gless by Kevin Parry/WireImage.com
One of these days, stunt-crazy Nip/Tuck is going to give a role to an unknown actor. This, however, is not one of those days.

Sources confirm to me exclusively that FX's slice-and-dice drama has sewn up two-time Emmy winner Sharon Gless for a four-episode arc to air during the show's upcoming fifth season (launching Oct. 30). The ex- Cagney & Lacey star will play Colleen Rose, an all-business talent agent who sets her sights on Sean. No, not romantically &mdas; professionally; she wants to represent him. (Although in the Nip/Tuck universe, the thought of Sharon Gless and Dylan Walsh having sex doesn't seem so strange. Icky? Yes. Strange? Nah.)

Gless' Nip/Tuck duties won't interfere with her costarring role on Burn Notice; production on the second season of the USA Network smash doesn't start up until mid-January, long after Gless' Nip/Tuck episodes are in the can.
