American wedding! Chris Klein is engaged, his rep confirms to Us Weekly. The American Pie alum popped the question to his girlfriend Laina Rose Thyfault after three and a half years together.

"Chris and Laina are very happy and look forward to celebrating their engagement over the holidays," his rep tells Us.

Klein, 35, and Thyfault, 29, first met at a mutual friend's wedding. The Wilfred star proposed in Venice Beach over the weekend.

As for when they will head to the altar? "Neither one is interested in a long engagement," a pal of Klein exclusively tells Us, "so they're shooting for a summer 2015 wedding."
