MAFS reunion: Alyssa pretends to gag while hugging ex-husband Duncan

Alyssa Barmonde will show her true colours when she reunites with her ex-husband Duncan James at the MAFS reunion.

A new trailer for the two-part finale, which airs Sunday and Monday, shows the single mother from Utah arriving solo for the dinner party.

She fakes a smile as she leans in to hug Duncan – who previously dumped her at the final vows – but makes it clear she isn’t happy about it.

After kissing his cheek, the 35-year-old reaches over his shoulder then pretends to gag in full view of her co-stars, including fellow bride Sandy Jawanda.

Later, when the cast members sit down for dinner, Alyssa bares her teeth.

‘Take off the mask!’ she yells with tears in her eyes, as Duncan, 36, is left speechless.

Also in the trailer, master gaslighter Harrison Boon rocks up with receipts in the form of damning texts he says will expose his ex-wife Bronte Schofield as a fraud.

He is clearly still nursing a bruised ego after Bronte walked out on him at the last dinner party following weeks of ups and downs.

Bronte puts on a confident façade in front of the other participants but admits her husband is out for revenge.

‘Everyone is on the chopping block tonight,’ warns Harrison, before Bronte says in a voice-over, ‘Harrison has said that he has dirt on me.’

It then cuts to Harrison holding up a print-out of leaked text messages, which have been censored for the promo.

The builder smugly asks, ‘Is that in frame?’

Married At First Sight continues Sunday at 7pm on Channel Nine and 9Now 

If you thought part one of MAFS’ final vows was an emotional roller coaster, just wait until all the brides and grooms return for the reunion event
