Julianna Margulies is coming back to ER as part of the show's final season.

The actress, who made a name for herself playing Carol Hathaway - the nurse that fell in love with George Clooney's Dr. Doug Ross - told Us Weekly that she and Clooney returned to the set recently for "two days and we had an amazing time."

The couple's storyline is "not sensationalistic," Margulies said. "John [Wells, executive producer] stayed true to what my feeling was about the characters."

Margulies revealed that the pair has twin girls, now in fourth grade.
