The Bachelorette and Bachelor in Paradise alum exchanged vows with his fiancee, Ally Lutar, on the evening of January 6 in Vancouver, Canada, Peoplereported.
In a sneak peek video of the wedding obtained by the magazine, Ally and Marcus walked down a candlelit hallway hand-in-hand while she was also holding a glass of champagne.
Both individuals were all smiles on their big day, which was also demonstrated when the bride and groom were shown sitting at their table together and toasting their glasses.
Marcus sported a traditional tuxedo with a black bow tie, and Ally stunned in a low-cut, mermaid-style gown with lace detail and buttons down her back.
Marcus, 29, proposed marriage to the British Columbia native in May 2017 with a customized halo-set diamond ring featuring a three-carat round center stone at Lynn Valley Canyon in Vancouver.
Marcus revealed at the time he had taken Ally, 35, on a mountainside hike and got down on one knee while walking across a suspension bridge over a waterfall.
Ally's parents and brother were reportedly waiting for the couple with bottles of champagne at the bottom of the river to celebrate upon the couple's return, and Marcus called it "the most incredible day" of their lives.
Marcus, who appeared on The Bachelorette in 2014 and then Bachelor in Paradise's first season that same year, revealed in July 2017 he had met his wife -- who owns a marketing and staffing agency -- through mutual friends at a July 2016 barbecue in Newport Beach, CA.
"The minute I met her I knew this was how you feel when you meet your wife for the first time," he previously told People. "Ally is gorgeous and strong -- I was completely drawn to her confidence."
The groom added, "She's also an incredibly successful business owner, and her business has allowed her the ability to travel -- luckily we met because of one of those work trips. Our first date was the following day at Javier's in Newport Beach... It felt as if we had always been together."
The couple wasted no time and immediately took things to the next level. Marcus said he had found the missing piece in his life, and so she moved into his home the very next day. He also joined her agency so they could work together.
"I can truly say I knew I loved her the day I met her," Marcus noted last year. "We moved so quickly because it's always felt so right and meant to be."
Marcus initially competed for Andi Dorfman's heart on The Bachelorette's tenth season and finished in her Final 4 suitors. Marcus then went on to film Bachelor in Paradise in Mexico in Summer 2014, when he met and fell in love with Lacy Faddoul.
Marcus proposed to Lacy on the season finale of Paradise, and they tied the knot during an episode of Bachelor in Paradise 2 the following year. However, the pair's marriage was not legally binding, and they eventually split.
Marcus told People in July 2016 that his relationship with Lacy was "toxic," later alleging that she had changed into a different person with different priorities following their engagement. Marcus insisted at the time they were "done for good" after more than two months of no communication at all.
