Ne-Yo and his wife, Crystal Renay, are as serious as they can be about giving their marriage another go -- TMZ's learned, they just walked down the aisle again, and they did it up big!!!
Witnesses tell TMZ ... Ne-Yo and the former reality star got re-hitched Sunday night on a rooftop at Resorts World in Vegas, exchanging vows and throwing a lavish reception for all their guests.
They had all the bells and whistles, too -- the room was filled with more than 10,000 roses, and we're told it took 3 days to set up. The enormous cake was about 8 feet tall with 4 different flavors!
The guest list included close family and friends like 'RHOA's Nene Leakes, Tammy Rivera from "Love & Hip Hop" and Melody Holt from "Love & Marriage: Huntsville."
And, the night wouldn't be complete without a performance from the singer ... of course, he sang some of his hits and danced along with his renewed bride.
The couple originally tied the knot back in February 2016. The "Sexy Love" singer filed for divorce in March 2020, but quickly withdrew it.
Waiting for your permission to load the Instagram Media.
Since then they've been working things out, and Ne-Yo ended up popping the question, for the second time, on New Year's Eve 2020. He's credited the pandemic for saving their marriage.
All that back and forth looks to be a thing of the past for Crystal and her man.
Congrats on the sequel, you 2!!!
