SUSAN SARANDON is reportedly slipping into her scrubs to star alongside GEORGE CLOONEY when he returns to medical drama ER for the show's final series.
Clooney starred as Dr. Doug Ross from 1994 to 1999 in the long-running series before leaving to pursue his movie career.
To celebrate the show which catapulted him into the A-List, the actor agreed to return to the role for the final few episodes before the series comes to an end after 15 seasons.
And he isn't the only Hollywood bigshot who will walk the wards - Sarandon is believed to have filmed scenes alongside the actor last week (begs19Jan09), according to E! Online.
It isn't the first time Sarandon has made a guest appearance on a hit U.S. TV show - she has starred in Friends, Malcolm In The Middle, Rescue Me and The Simpsons.
