They wed on Saturday at the Good Shepherd Catholic Church in front of 20 close friends and family.
A witness tells People.com, "She (Durham) looked like a princess and beyond stunning. Mark looked ecstatic."
Durham wore a Marchesa gown for her big day. The ceremony lasted a little over 45 minutes.
The actor put a hold on his new film The Fighter in his native Massachusetts to exchange vows with his longtime partner.
Wahlberg and Durham have been together since 2001; they have three children together: Brendan Joseph, who turns 1 next month, Michael, 3, and 6-year-old Ella.
Arriving at the church, the movie star told fans, "(I feel) pretty good... It's good."
