Former ER lovers George Clooney and Julianna Margulies are still crazy for each other after all these years – as pals, that is.
The actors – who played the dashing Dr. Doug Ross and his onscreen love, nurse Carol Hathaway – recently reunited for the medical drama s final season.
“It’s been nine years and it was like we’d never been apart,” Margulies told eyebrow guru Ramy Gafni, who recently tended to her famous brows at his RamySpa in Manhattan.
“She said, ‘The chemistry was still there.’ She said she loves him to pieces and that he’s such a great guy,” says Gafni.
In the final season, viewers will finally find out what became of Ross and his onscreen flame, who never married in the earlier episodes.
Clooney, 47, left the show in 1999 for movie stardom, winning an Oscar for 2005 s Syriana. Margulies, 42, who exited ER in 2000, and her husband, attorney Keith Lieberthal, had their first child, Kieran, in January.
NBC and Warner Bros. declined to comment on the casting of ER’s final season. But in Jan. 26, Clooney told PEOPLE of his return to County General, “It was fun to be back and it was good to see those guys.” Margulies’s rep has previously confirmed she will return to the show.
The final episode of ER will air April 2 on NBC.
