Drama escalated within seconds on Married At First Sight as groom Jordan dropped the bombshell that he'd kissed another bride behind new wife Alexis' back.

During Wednesday night's dinner party, viewers saw tension bubbling between the newlyweds, with a distinct frostiness between them as they arrived to greet the other couples and Alexis admitting to the girls that things had not been going well.

Nikita ended up in a screaming row with Jordan over his treatment of Alexis, with her then being thrown off the show, as MAFS fans saw Jordan chat to Megan and Alexis flirt with Nikita's husband Ant.

All the couples had some big choices to make in the commitment ceremony which aired on E4 on Thursday night and it was during that that Jordan came clean.

He told the other couples, including Megan and her husband Bob, who had just decided to stay together: "During the party I found myself having a conversation with Megan.

"We were very similar in a lot of ways and we actually shared a kiss."

Sitting next to Megan, Bob instantly raged: "What a b*tch!" as Alexis shook her head.

Jordan continued: "She said the relationship between her and Bob wasn't working for the reasons that she has been trying but Bob hasn't been doing anything back.

"But what I've seen tonight was Bob protecting someone that didn't deserve protecting. And how I've seen her treat him compared to the story I heard. How I feel is that I don't want to be mixing with somebody like that."

He then admitted he had previously chosen to 'stay' in the hope of pursuing something with Megan as Bob demanded that his choice be changed to 'leave.'

Expert Paul C.Brunson was forced to jump in and shout: "Folks, let's respect the forum OK?!"

As the show returned from an ad break, Bob walked out of the room to be consoled by the other grooms as Megan offered no apology, before then admitting she thought there was 'a connection to explore' with Jordan.
