Things are really heating up with these two!

Sofia Vergara and boyfriend Joe Manganiello headed to Mexico for a romantic getaway over Labor Day, and the Colombian actress wasn't shy about sharing pics of their love fest on her Who Say account!

The hot pair bunked at the Zoetry Casa del Mar Los Cabos and enjoyed massages and private dinners on the beach, as well as some pool and ocean time. We would be willing to bet there was a fair amount of time spent in the bedroom, too!

"They always looked like they were very happy, smiling and laughing. They really seemed to be enjoying being together," a source told People.

We have a feeling they will be together for a while!
