Marion Ross will soon be popping up on Grey's Anatomy, according to TV Guide.
The 81-year-old actress, beloved for her role as the mom on Happy Days, and more recently seen as the mother of Brothers & Sisters' Nora Walker (Sally Field), Marion will not be crossing over, per se, but playing a new character altogether at Seattle Grace.
"Marion plays an older patient who has an amazing epic love story with another older patient in the hospital," says Grey's Anatomy creator Shonda Rhimes.
"She did beautiful, beautiful work and was delightful."
Marion Ross' take on her Grey's Anatomy appearance?
"Our two gurneys pass each other – and there is a man I had a romance with fifty years ago," tells Marion, who shares scenes with Sandra Oh's Cristina Yang.
"It was such a joy for me."
She appears May 13.
