Yet she set the record straight by insisting that the couple have not tied the knot, before hinting that their big day could be right around the corner.

Sheridan explained: 'I do wear two bands on my hand, mainly because this one is too big and it does keep it on.

'But Jamie does wear his wedding ring, we're not actually married, we just do it. My friends do that but no one actually talks about it...

'We didn't think about it when we took a picture and put it on Twitter and then of course everyone thought that we were married.'
