Carl, from Tiger's Bay, and Christine, from Poleglass, first met at Kelly's nightclub in Portrush seven years ago and were married in a humanist service at The Old Inn in Crawfordsburn on Sunday.
It came a week after Carl retained his European super-bantamweight title with a big win over Jeremy Parodi at the Odyssey Arena in Belfast.
Family and friends attending the wedding included their two-year-old daughter Carla, Carl's manager Barry McGuigan and his Olympic-medal winning best man Paddy Barnes.
Speaking to UTV's Ruth Gorman ahead of the big day, the couple were both excited and nervous.
Especially about the best man's speech.
"He's a liability, Paddy," Carl said of his closest friend on the boxing circuit.
"The only good thing is that he talks that fast, people might not know what he's saying ..."
But, coming from different backgrounds, both Carl and Christine were also keen to prove that doesn't have to matter.
"If younger kids do look at us and see us as role models, it can only be a good thing," Christine said.
"Because we just go to prove that, no matter where you're from, you can be friends and you can be in a relationship.
"We met, we were like 18/19 - we were just teenagers - and to grow together into a wee family, it's the nicest feeling ever.
"Carla's definitely the best thing that's ever happened to me and to Carl and it's just amazing to look at her and see ourselves in this wee person."
