The new series of Married At First Sight UK has reportedly been rocked by a cheating scandal.

The sixth UK series of the unconventional dating show is adopting the hugely-popular Australian version of the format, moving to E4 and airing every weeknight over four to five weeks.

Filming recently got underway at a mansion in the South of England and according to The Sun, major rows erupted after it emerged that two of the newlyweds cheated on their new spouses with each other just days after tying the knot.

"Two housemates have been sneaking around with each other," a source told the newspaper.

"But they couldn't keep it quiet, and it's all been kicking off in the house."

The series is expected to air on E4 this autumn.
