The couple's family were the only guests at the private affair, held Saturday in Grand Lake, Colorado, said Allen's publicist, Marleah Leslie. Allen's 17-year-old daughter, Katherine Dick, was among the attendees.
It is the first marriage for Hadjuk, 39, and the second for Allen, 53. He was previously married to Laura Deibel.
Hadjuk and Allen appeared together earlier this year in the children's action film "Zoom."
Allen will be seen in the upcoming "The Santa Clause 3" with Martin Short. He recently finished filming Disney's "Wild Hogs" with John Travolta, Martin Lawrence and William H. Macy.
