Happy 51st birthday, Julianna Margulies! The Good Wife star is celebrating a major milestone today, but she still looks just as stunning as when she caught George Clooney’s eye on-screen in ER.

The star became a household name when she started on the long-running medical drama in 1994, acting as Nurse Carol Hathaway for six seasons of the hit run. She garnered dozens of awards show wins and nominations for the role, including a SAG Award for Outstanding Performance by a Female Actor in a Drama Series.

After leaving the show, Margulies found a new TV home in the lead role of Alicia Florrick in the legal drama, The Good Wife. With a Golden Globe and two Emmys under her belt for the role, this stunning star is one of TV’s most awarded actresses.
