Patrick Dempsey turned into the real McCrabby when a die-hard “Grey’s Anatomy” fan spotted him lunching alfresco at the swanky Chateau Marmont!
The innocent fan gushed at his table, “I can’t believe it’s actually McDreamy — in the flesh!”
Said a garden gab: “The starstruck gal was so excited to meet the famously handsome actor, but her smile faded fast — he cringed, snapping, ‘Please don’t call me that!’”
Explained the insider: “Patrick hates the old nickname. Especially since power producer Shonda Rhimes brutally made the dreamboat doc draw his McFinal breath!”
