Audrina (31) glowed in a romantic, lace boho gown by Australian designer Pallas Couture and styled her brunette locks in loose waves, with a red flower tucked behind her ear.
The MTV star wed Australian BMX biker Corey at the top of a hill in a dreamy botanical garden overlooking the Pacific Ocean.
The couple welcomed their first child Kirra Max Bohan in June, and she was adorably involved in the wedding ceremony.
None of Audrina's co-stars from The Hills were present at the wedding, with the television personality telling Fit Pregnancy and Baby magazine that they wanted to only invite close friends and family.
"We just finalized the guest list, and it's about 130 people, mostly family," 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 and Corey have been in an on/off relationship for eight years and became engaged in November.
