Kimberley Walsh has revealed to fans she is expecting her first child.

The former Girls Aloud star, who made it to the finals of the 2012 series of Strictly Come Dancing, announced her baby news just days after her ex-bandmate Nadine Coyle became the first member of the group to become a mother.

Kimberley posted a message on Twitter to tell fans that she and boyfriend Justin Scott – formerly of boy band Triple 8 – were to become parents.

She wrote: “Justin and I are so happy to let you all know we are having a baby. Couldn’t wait to share our lovely news with you all.”

Ex-bandmate Cheryl Cole tweeted: “@KimberleyJWalsh FINALLY, I thought at one point I was going to burst,” while Nicola Roberts, who also sang in the group, tweeted: “Secrets out!! I am BURSTING with love! Kimberley & Justin are having a baby! I am so happy and so literally beside myself with excitement!!!”
