Marvin and I could NOT be more thrilled to announce that we are expecting our first child mid next year.

We have always dreamt of being parents and the news is the best early Christmas present we could have asked for.

I know Marvin is going to be a great dad and we're so excited to start a family.

Fellow celebrities were quick to offer their congratulations on Twitter.

It is the second big baby news in the pop quintet this year after Una Healy gave birth to Aoife, her daughter with England rugby player Ben Foden, in March.
