The couple first met when they took part in the reality TV show's seventh series in 2006 - back when the show aired on Channel 4 - and the pair "couldn't be happier" to be adding to their brood.

Grace - who has kids Georgiana Slone, nine, son Spencer Michael, five, and daughter Allegra Portia, three, with Mikey - said: "People think we're mad to have a fourth, and maybe we are, but we couldn't be happier.

"It's been a pretty good pregnancy, when you spend all day running around after the kids, you don't have time to think about anything else, they've kept me more than occupied.

"We're all delighted and can't wait to meet our new little one."

Grace is due to give birth on January 8th, and the pair were "shocked" at how quickly they fell pregnant.

She added to OK! magazine: "We knew we wanted another baby so we started trying but it happened quickly so we were both shocked at how fast it happened.

"I think Mikey thought there would have been more practising."

Grace and Mikey were just 20 and 23 respectively when they first met on 'Big Brother'.

They married in 2009, after getting engaged just four months after the reality show.

Grace and Mikey now run a dance school in Liverpool, where they live together.

Just two weeks ago, Grace admitted she is "so proud" of her kids.

She posted a picture on Instagram of her children returning to school, and she added the caption: "Late to the party of posting pics of the kids it’s taken me 2 days to get back into the swing of things after 8 weeks of Summer holidays . Little Allegra starting pre school , Year 1 and Year 5 so proud of them all xxx #backtoschool

First time in 5 years I won’t have a child at home (sic)"
