Watch moment MAFS bride Amy explodes in fiery four-letter tirade after Lacey drops bombshell about husband Luke

MARRIED At First Sight star Amy is left furious after fellow bride Lacey drops a bombshell tonight.

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

Luke was coupled up with Lacey for the task, while Amy went to stay with Adam.

The couples reunite for the dinner party tonight, but Lacey brings to light what Luke told her about him wanting Amy to loosen up.

Amy, who admitted that Adam treated her like a "princess" during her time with him, was already upset that she was not receiving the same treatment from her husband Luke.

During a conversation with Lacey, Kristina and Sacha, Amy says: "The thing that made me think, was that Adam was treating me like a queen and he said to me 'Amy, I'm not doing anything for you that I don't do for Polly'.

"It made me think, I can't wait to ask Lacey, what's Luke done for Lacey."

Lacey then spilled the beans and says: "Another thing, you know that picture of me and Adam, he said that he was actually a little bit envious deep down.

"He wanted a partner like that."

Amy gasped and said she needed a minute to comprehend what her husband had said.

Sacha pointed out: "That's contradicting himself massively."

Amy tried to clarify, saying: "So at the beginning you weren't classy and he was proud of me for being classy, but now he wants me to be like you because I'm too classy."

Lacey simply replies: "Yes," leaving Amy confused and hurt.

Lacey was referring to the photo that was taken between Lacey and Adam when they were salsa dancing on the separate days.

Luke described that initially as not being classy.

Expert Paul C Brunson explains: "The fact that Amy sees that Like likes the way Amy acts, is confusing to Amy."

A furious Amy admits to the girls: "That comment about him being envious because he wants me to be like you is f****** bull***."

But it looks like only half of the conversation was relayed.

As Luke was not saying that he wanted Amy to be like Lacey, but simply said that he would have liked a wife to be "less stiff" and someone he could dance with.

He also told Lacey during their chat that he wanted Amy to relax more, so he could see a different side to her.

Luke also apologised to Lacey for saying that dancing with another man was "not classy".

Elsewhere, Amy enjoyed a night with Adam and the pair shared his marital bed, which left Luke hurt.

While Adam went lingerie shopping for Polly with Amy, but the redhead was left in floods of tears after she found out her husband went underwear shopping with another woman.
