The singer got hitched in Brighton this Bank Holiday weekend to girlfriend Bianca Murphy.
Sharing pictures of the big day online, Frankie posted snaps to Instagram with the caption: "Mr & Mrs"
Frankie is seen in a black suit and gold shirt, matching his partner's golden wedding dress.
The pair got engaged back in January of this year.
Bianca announced at the time: "We're getting hitched!!!!
"Cannot wait to spend the rest of my life with you, you AMAZING beautiful human, I LOVE you unconditionally & Eternally"
The marriage follows Frankie's time on Celebs Go Dating just last year where he was seen looking for love.
The series ended with Frankie hooking up with fellow celebrity dater Charlotte Dawson although their fling soon ended with a messy split.
Shortly after the show wrapped up, Charlotte very much blamed Frankie for the break up.
In an interview at the time, she branded him an "idiot" and revealed: "I don't speak to him."
She explained: "We had a good connection - as you could see on Celebs Go Dating, it was very genuine and real. I didn't have him down for being a showmance type of person, so it was a shock. It was horrible."
Speaking to Star magazine last October, Charlotte went on: "I'm far too good for Frankie.
"We had proper sexual chemistry, so it's annoying. If I saw him tomorrow, though, we'd probably end up sleeping together - then I'd probably tell him to f**k off."
Celebs Go Dating airs on E4.
