These two just can't keep their hands off of one another!

On Tuesday night Sofia Vergara and Joe Manganiello were among the many celebs who attended Justin Timberlake's concert at the Staples Center in Los Angeles, and the couple looked like they were about to make out when X17 photographers snapped them in the parking lot. Seriously -- Sofia looks totally lovedrunk in these photos! We NEVER saw her like this with former fiance Nick Loeb...

And from celebrating her birthday together to a romantic trip to New Orleans, Sofia and Joe both seem to be falling head over heels -- and fast! The lovebirds first met at the White House Correspondents Dinner in May, when the Modern Family was still engaged to Loeb, and since then we've also spotted them at Lady Gaga's L.A. concert and out to dinner. "It's very, very new. They're having fun and getting to know each other," a source told Us Weekly shortly after the news broke that the two were dating.

Hmm, seems to us like they're ready to move in together ... if they haven't already!
