Chris Klein is married!
The American Pie actor, 36, and his girlfriend of four years, travel agent Laina Rose Thyfault, 30, tied the knot Sunday in Montana, his rep confirms to PEOPLE.
The couple exchanged vows in front of 115 guests at the Rainbow Ranch in Montana at an outdoor church with vintage pews and a custom doorway on the banks of the Gallatin River.
“Laina and Chris wanted to stay true to the nature of Montana and chose native grasses, sage and flowers in a soft color palette to reflect the beauty of Montana,” their wedding planner Jennifer Horsley of Habitat Events tells PEOPLE.
Klein, who wore a custom Shoreditch London three-piece suit to his nuptials, began dating Thyfault after meeting her at a mutual friend’s wedding; the two announced their engagement last December.
