Talk about one sexy Hollywood couple!
"They just started to hang out," a source told People.
An Us Weekly source said, "It's very, very new. They're having fun and getting to know each other."
Us Weekly reported that the "Modern Family" actress and Joe met at the White House Correspondents' Dinner in May, but Sofia was dating then-fiance Nick Loeb, who she has since split with.
According to another Us source, Joe has had an eye for Sofia for a while.
"Sofia is Joe's dream girl!" the source explained. "He's been smitten with her for years. He's always had a huge crush on her. Things are going well for them so far."
Joe was engaged to model/actress Audra Marie in 2010.
