She wrote excitedly: "Now I am officially grounded for rest of pregnancy, not that there's long left!□ in 3rd trimester, know it'll fly by x [sic]"

According to the Atomic Kitten's Twitter posts, she's busy planning a baby shower in the meantime - although she's still found time to spend some quality time with her favourite boys.

Yup, while this is Ritchie's first child, the unborn baby girl will be Natasha's fourth child.

She is already mum to Josh, 10, with ex Fran Cosgrave, Harry, 8, from her relationship with Gavin Hatcher and three-year-old Alfie, who she had with ex husband Riad Erraji.

And the expectant mum, who has confessed she is pregnant with a baby girl this time around, has been making sure to have plenty of fun with her little lads.

Bless them.

It's not long to go for Natasha and Ritchie - are you excited?
