The MTV reality star, 31, tied the knot with her long-time boyfriend, Australian BMX racer Corey Bohan, 34, at a ceremony in Hawaii on Saturday, 5 November.
According to E! News, the nuptials took place at a botanical garden overlooking the ocean. None of Audrina's The Hills co-stars were in attendance.
Audrina and Corey have been together around eight years and have a daughter, Kirra Max Bohan, who was born in June 2016.
Corey actually appeared fleetingly in The Hills and was seen going on a date with Audrina before she 'dumped' him. But she recently explained to ET Online that was just for the cameras, as she didn't want their relationship to play out on TV.
Audrina recalled: "I kind of told him, 'We're going to film one more time. I'm gonna kind of let you go, because I don't want to involve you in what's going on or about to happen.' Corey was such a good guy and I was like, 'He's so nice, it's not fair to involve him all of this drama.'"
So far Audrina and Corey have yet to comment on their marriage.
But Audrina did a lengthy interview with Fit Pregnancy and Baby earlier this year, where she dished on honeymoon plans and why none of her The Hills co-stars had been invited.
"If we take a honeymoon, we're definitely bringing [Kirra] and my little sister, so she can watch the baby while we go out to dinner or snorkel," revealed Audrina.
As for her MTV co-stars not making the guest list, she said: "As far as friends go, we only invited the ones who've been there for us in the past year and who will continue to be there for us for the next 30. So, no one from The Hills made the cut. If we were doing a really big wedding, I'd invite them, but we're keeping it intimate.
Audrina found fame on MTV's reality show The Hills, which followed the lives of a group of friends in Los Angeles, including Lauren Conrad and Heidi Montag. Audrina remained on the show for the entire six series.
After The Hills, she went on to star in one series of her own reality show, Audrina, and take part in Dancing with the Stars, the US version of Strictly Come Dancing. She's also appeared in the movie Sorority Row and hosted a late night travel series called 1st Look.
