The Big Reunion stars Natasha Hamilton, 31 and Ritchie Neville, 34, revealed their pregnancy joy at the beginning of last month after dating since last year.
And, last night, Natasha shared an image of what her unborn baby would look like at 20 weeks on Twitter.
She captioned the image: "Your baby @ 20 weeks! Just had scan too & everything is looking great.
"Feeling really blessed & thankful right now xx"
It's lovely to see how excited Natasha is about her pregnancy. Just a few weeks ago, the mum-of-three (soon to be four!) shared a sonogram image on Twitter.
She wrote: "Our little bundle of joy. Half way there now, so excited to meet my baby x"
Ritchie, 34, who moved from Australia to the UK for The Big Reunion tour, is looking forward to becoming a dad.
"I want to be a hands on dad.
"Natasha's stuck with me forever now, no matter what happens."
Natasha is already mum to Josh, 10, with ex Fran Cosgrove and Harry, 8, from her relationship with dancer Gavin Hatcher.
The singer split from ex husband Riad Erraji last year after 6 years. The former couple are also parents to 3-year-old Alfie.
