The 36-year-old singer tied the knot at the luxury Terranea Resort by the sea at a ceremony witnessed by family members and their closest friends.
Ne-Yo told PEOPLE magazine: “We can’t wait to start our life together. We’re looking forward to just being each others’ best friend.”
The American R&B singer wore a grey suit with black tie for the special occasion, while his expectant wife – who is nine months pregnant – wore a traditional white gown that featured embellishments and sheer lace sleeves.
Ne-Yo first met his wife to discuss working together on his album ‘Non-Fiction’, which was released last year, and he admitted it was a case of love at first sight.
He told People: “I kind of knew right away. From that first encounter, I knew there was something different about her, something special.”
Meanwhile, Crystal explained how her pregnancy created a headache for her dress designer.
She shared: “When I went to my first fitting, I had actually just found out the day before that I was pregnant.
“So from the beginning of the whole dress process, we knew that it would be a growing belly.”
