"Modern Family" star Sofia Vergara is engaged to marry one of the hottest guys in town ... so why is she hiding her massive engagement ring?

"True Blood" star Joe Manganiello popped the question over the holiday weekend after just six months of dating (and Sofia only broke up with her other fiancé less than two months before that).

Vergara was spotted at the airport with her ring turned around so nobody could see it. 

The ring is rumored to be at least 10 carats ... who's gonna miss it?
