The upcoming three-part Vanderpump Rules reunion show looks to be as dramatic as ever this season.

In a preview released on Wednesday Scheana Shay comes face-to-face with estranged husband Michael 'Mike' Shay for the first time since filming season 5 - and accuses him of cheating.

In the clip the 31-year-old star looks tearful as she announces to her cast mates that she caught Mike texting another girl.

Vanderpump, 56, is also seen telling Bravo host Andy Cohen that if she were Scheana, she would have made her husband sign a prenuptial agreement.

'Well, I would have had a prenup if I would have been married to Shay, let’s be honest,' said the restaurateur.

Scheana admits she had 'nothing to lose at the time'.

Sitting across from his estranged spouse Mike looks away and says quietly, 'I can’t even look at you right now.'

It's a tense scene for the duo who announced their split in November following an incident where Mike went missing for six days.

Their wedding was filmed July 27 2014 and aired on the show but it wasn't long before cracks started to show in their relationship when it emerged Mike had been abusing painkillers.

Scheana is now dating actor Robert Parks-Valletta and was spotted packing on the PDA with him in Hawaii this week.
