The town in North Ayrshire has been dubbed the “most adulterous” in Scotland by a dating website which specialises in arranging affairs.
Illicit Encounters, which claims to have more than one million registered members in the UK, said more Irvine residents had signed-up for its services than any other Scottish town.
In second place was Leith in Edinburgh and Livingston in West Lothian was third.
Irvine, 30 miles south-west of Glasgow, was fourth in the full list for the UK with Stratford-upon-Avon in Warwickshire coming out top.
Illicit Encounters spokesman Christian Grant claimed “a lot of Scots are trapped in unhappy marriages”.
He added: “We tend to find that new towns in Scotland are hotbeds for cheating. Livingston is another new town where adultery is rife.”
