On a break from filming the hit series Grey's Anatomy, Patrick Dempsey stays more or less incognito Tuesday, enjoying a day of solitude and strolling through chilly streets of Paris, France. If he weren't so darn McDreamy, he might be anonymous in that getup ... but his handsomeness is inescapable.

Stylish as ever, Patrick Dempsey does a little sightseeing in France.

While fans may be split over whether they prefer to see Patrick or Heroes' Milo Ventimiglia shirtless, there's no disputing that both of these hunks' TV shows have become enormously popular - and their hotness is a big reason.

Patrick, Ellen Pompeo, Katherine Heigl and the rest of the Grey's Anatomy cast return to the airwaves tonight at 9 p.m. on ABC.
