‘He’s never been happier’ say MAFS UK fans as they predict trouble for bride and groom after couple swap

MARRIED At First Sight fans predict trouble for Polly and Adam after his shock comments on tonight's show.

This week the remaining couples spend some time apart from their spouse and with another bride or groom from the experiment.

Partner swap week is a chance to get a taste of how another couple functions day-to-day, by spending time in the company of another spouse.

Adam found out that he was partnered with Amy, leaving wife Polly fearing for the worst.

Polly admitted she was not "jealous", but said she felt "insecure", especially of how beautiful Amy is.

She told the camera: "My stomach has naturally dropped, I'm not a jealous person but Amy is stunning, absolutely gorgeous woman and I don't want to go back to square one feeling insecure about myself.

"It is very strange having another woman come into my home, it is very intimate."

She went on: "There could be a touch of jealousy, but I'm going to try and keep a cool head."

After moving in together, Adam was quick to discuss his and Amy's sleeping arrangements.

Amy agreed that she would be happy to share Adam's marital bed, leaving the lad chuffed.

He later makes a cheeky comment about not be able to "sleep in his clothes or wedding ring".

Amy then took Adam lingerie shopping in a bid to ignite his flame with Polly.

But Adam got sidetracked by asking Amy what her underwear size was and joked that she should try on the lingerie.

Some E4 viewers said it was the happiest Adam had looked throughout the whole process.

One wrote: "Adam and his cheesy grin over Amy, happiest and most smiley his been this whole show is hilarious."

A second posted: "Adam finally happy to be sharing a bed with someone he wants to touch."

A third commented: "Adam looks like the cat that got the cream."

"Adams grinning like the Cheshire Cat - don’t think I’ve ever seen him so happy," this viewer said.

Another added: "Adam wants the bedroom activities with you Amy not Polly."

While out shopping, Adam messaged Polly to ask her what size she was.

Polly was left in floods of tears and upset that Adam was finally opening up about intimacy with another wife in the experiement.
