A spokesperson for the model-singer told Us Weekly that she and Friedman wed at the Hollywood Castle in LA on Sunday (September 30).
D'Amato said in a statement about her nuptials: "Today was wickedly magical! I'm overjoyed and blessed to find my soulmate and have a celebration that includes our close friends and family."
Dr Drew Pinksy, ex-Hollywood madame Heidi Fleiss and former America's Next Top Model contestants Alexandria Everett and Bre Scullark were among the stars in attendance.
D'Amato famously appeared in America's Next Top Model's fifth cycle and then returned to win this spring's All-Star season.
She is also a recording artist, having contributed the track 'Can't Touch It' to an episode of Entourage.
