“How To Make It in America” hunk Bryan Greenberg and “The Hangover II” hottie Jamie Chung were spotted canoodling at the SXSW film fest in Austin, Texas. When Greenberg arrived at a premiere of Chung’s “Eden,” he kept a low profile by skipping the red carpet. But the couple showed a bit of PDA with “some hand-holding and a few kisses” after the true story of an abducted teen debuted at the Stateside Theatre. Greenberg’s rep said, “Bryan and Jamie are just friends.”
