And clearly the romance of the day rubbed off on Jacqueline and Dan as they posted a string of very loved up images to Instagram during the reception!
Jacqueline - who appears to have been a bridesmaid - looked as beautiful as always in her lilac dress, showing off a glowing tan from her holiday abroad with Jac and Ella, three months.
Images posted by both Jac and Dan show them kissing, cosying up and generally looking blissfully happy.... Hmm. Will they be the next to announce an engagement after this?!
Their happy day out came as Dan's old TOWIE co-star Gemma Collins defended him in a new interview and suggested he be allowed to return to the show.
Dan was suspended and then axed from the ITVBe series following allegations he'd been verbally abusive to his ex-girlfriend, the mother of his son Teddy, one.
In a chat with The Mirror, co-star Gemma said: "People say things in temper. That's what all the Essex boys say to their girlfriends. Death threats? Yeah. That's Essex boys for you. I've had boyfriends say to me if I ever leave them they will kill me. In Essex it's a normal thing.
"He was never going to kill her and I think he deserves to make a comeback to the show."
She later clarified her remarks via Twitter:
"Tweeps the story this morning has been taken out of context BIG time. All I'm saying is Dan is just a young guy, he's got lots to learn. Not saying what Dan said was right but we all says things we wish we could take back that come out in the heat of the moment. It happens!
"No woman/man should be threatened but sadly things do happen & I was just being REAL about it as I hear it all the time from friends."
