Who needs Hollywood dudes, anyway?

Amanda Seyfried -- whose exes include actors Ryan Phillippe and Dominic Cooper -- has been quietly dating Andrew Joblon, an NYC-based real estate exec, two sources confirm to Us Weekly.

Seyfried, 25, was at Joblon's side Tuesday at the Eric Trump Foundation's Golf Invitational & Gala at Trump National Golf Club in Westchester, New York. According to The New York Daily News, the hot new duo kept their distance during the cocktail reception but cozied up to one another once dinner began.

As Bret Michaels entertained the crowd, Seyfried reportedly rested her head on Joblon's shoulder and ran her hand along his arms.

The affectionate outing shouldn't come as a surprise, given that Joblon, 28, was spotted rubbing Seyfried's inner thigh during the U.S. Open on Aug. 5.

"They were very close at times," an eyewitness tells Us of the pair, who sipped on Moet & Chandon champagne during the event. "No one saw them kiss, but they were definitely cute and he was getting her drinks."
