Richard Search, a CNN anchor, married Chris Pepesterny, his old male partner.
Quest made the announcement on Instagram, writing: "We said 'I Do' at the weekend. Best day of our lives."
The two took part in May 2019 after the journalist's proposal for marriage was accepted by his lover.
In March, they had to delay their marriage, but they vowed to tie their nest before the year's end.
At that time Quest revealed that "We were going to marry Chris and I in London today; we had to postpone that. Unfortunately, we had to do that. We were going to marry a bigger group later this year. I wanted to remember that both of us were facing such tough times in several different ways. This, too, is going to happen."
