Steve Stifler is single again. Nearly a year after announcing their plans to marry, Seann William Scott and former Victoria's Secret model Lindsay Frimodt have called off their engagement, Scott's rep confirms exclusively to Us Weekly. After less than a year of dating, the American Reunion actor, 35, proposed to the beauty in early 2012 during a beach vacation.

"They remain friends," a source tells Us of the breakup. "It was a very amicable split."

Scott happily confirmed their engagement at the March 2012 premiere of American Reunion. "I don't how I got a girl like my fiancee," Scott said. "She hadn't seen American Pie. Thank god. Otherwise, I probably wouldn't be engaged." (Scott reprised his role in the sequel as crude party boy Steve Stifler alongside Jason Biggs, Tara Reid, Alyson Hannigan and Chris Klein.)

Before his romance with Frimodt, Scott had been linked to actresses Jaime King and January Jones.
