"Greek" actor says he's dating Stephanie Pratt of "The Hills. She says he isn't.

Andorra/Chestnut Hill raised actor Gregory Michael told us he is dating Stephanie Pratt of MTV's "The Hills," though he hates reality TV.  Pratt told us via Twitter this afternoon that the pair are not dating.

"I'm not a big reality show person. I don't watch it and I don't endorse it. Who she is has nothing to do with what she does," Gregory, who stars on ABC Family's "Greek," says of Pratt, who was in A.C. Saturday hosting a party at Dusk inside Caesars. Gregory says the pair are dating but "aren't at the girlfriend/boyfriend stage yet" and met around Thanksgiving while doing charity work in Los Angeles. "I had no idea who she was when I first met her," says Gregory who has yet to meet Pratt's brother Spencer Pratt or his wife Heidi Montag. The actor, born Gregory Michael Hosmer, says his two years at Penn State were "way more wild" than the college life on "Greek," which airs Mondays. He attended Norwood Fontbonne Academy for elementary school and La Salle College High graduating in 1999 and after his time at Penn State he transferred to NYU then left school for a job acting at Disney World.

"One of my biggest dreams is to work in Philadelphia either shoot a movie or series in Philly," Gregory says. He recently worked with Fred Savage, who directed an episode of "Greek" and told him how much he'd love to work on "It's Always Sunny in Philadelphia," which Savage directs. He gets to town often and claims to fly in sometimes just for cheesesteaks from Dallesandro's (Henry & Wendover). The actor says performing at the Walnut Street Theatre, in shows such as the "Music Man" and "Blood Brothers" "helped more than anything else" in honing his skills.
