Life & Style can exclusively reveal that Entourage star Perrey Reeves, 41, is dating actor Johann Urb, 35!

Multiple eyewitnesses tell Life & Style about the pair's recent hot and heavy outings together.

"They were at the Seven Psychopaths premiere together in LA on Oct. 1," one eyewitness tells Life & Style.

Just one evening later, another eyewitness saw them locking lips at an event!

"She snuck in with a girlfriend to the Empire magazine party about an hour after Johann arrived," the second eyewitness, who was at the Netflix-sponsored bash celebrating the launch of Empire’s U.S. edition for iPad, tells Life & Style. "Almost immediately, she was sitting and chatting with him by the pool. About 30 minutes later, she was sitting with her legs draped over Johann's.

"They were super happy, smiling and affectionate," the eyewitness adds. "They were all over each other and making out."

And the couple had no problem with their public displays of affection.

"They stayed until the end of the party, just the two of them embracing one another on one of the couches in the corner," the eyewitness tells Life & Style.

Perrey, who's known for playing character Ari Gold's wife on the hit HBO series as well as Will Ferrell's on-screen wife in Old School, dated actor David Duchovny in the mid 1990s. She even appeared on David's hit show, The X-Files, in 1994, when they were dating.

Johann starred alongside John Cusack in the 2009 flick 2012 and currently appears in Resident Evil: Retribution. He married model Erin Axtell in 2007, but the pair divorced in 2010.

Coincidentally, as listed on IMDB, Johann will star on an episode of Showtime's Californication next year — which just happens to star Perrey's ex David.
