He isn't a doctor, but Patrick Dempsey played one on TV, and he's got some medical advice he's heeding himself.
Dempsey, who played Dr. Derek "McDreamy" Shepherd on "Grey's Anatomy," posted a selfie to Instagram showing off his blue eyes -- and his checkered face mask.
Mimicking one of his character's catchphrases, Dempsey captioned the pic, "It's a Beautiful Day to Save Lives," adding the hashtags #WearAMask, #COVID19, and #YourActionsSaveLives.

Dempsey's post comes after his former co-star Eric Dane, who played Dr. Mark Sloan on the hit medical drama from 2006 to 2012, shared a photo of the two to emphasize the importance of social distancing.

Although Dane did not disclose when the photo was taken in the caption, many super-sleuth fans speculated that it was taken while the pair were shooting season four of the show. Since leaving "Grey's Anatomy," both actors have continued pursing projects in film and TV.
Dane recently starred in season one of the popular HBO drama "Euphoria," and Dempsey currently stars in Sky Studios' new TV series "Devils."
