The TV star exchanged vows with Angela Stacy in the woodlands surrounding the Calamigos Ranch on Friday (14 June).
Matt married his girlfriend of four years in front of 145 guests in a lavish ceremony deep in the woods of the exclusive Malibu resort.
He tells Life & Style: "It was the happiest day of my life.
"Everything went perfectly. It was amazing to do this in front of our closest friends and family."
Angela immediately changed her surname to Lanter on Twitter and posted a stunning black and white picture of her on her wedding day wearing her veil.
She wrote: "Love my husband."
Matt proposed to Angela last summer in Paris.
The couple are in the process of relocating to New Orleans, where Matt is filming his new TV show Star-Crossed.
Congratulations Matt and Angela!
