Things are heating up for the hottest couple of the moment: actor Aaron Eckhart and model-turned-actress (and now jewelry designer) Molly Sims.

Reports first circulated last week that they shared an intimate dinner in Baton Rouge, followed by a report Tuesday that Sims gushed to friends, “Aaron’s a great guy!”

Sources have now confirmed to PEOPLE that the two are in fact a couple and have been quietly dating for a few weeks.

Eckhart starred in Love Happens and Sims is currently promoting her new line of jewelry, Grayce.
