Let's make this birthday one to remember.

55 years old (Born on November 10, 1969)

Happy Birthday, Ellen Pompeo! You've cured us of boredom (and sometimes broken our hearts) weekly as the incredible Dr. Meredith Grey on "Grey's Anatomy." With countless emotional surgeries and passionate monologues under your belt—seriously, nobody narrates elevator drama quite like you—you've proven you're exactly what the doctor ordered.

Your dedication made medical scrubs fashionable for nearly two decades and taught millions that life is too short not to dance it out in a break room occasionally. Here's hoping this birthday tops all previous seasons—and remember: age may be just a number…but lucky for you, that's one diagnosis McDreamy never worries about!
