Kimberley Walsh showed off her baby bump on Twitter yesterday (July 21).

The Girls Aloud star took a photo of the side profile of her bump, and asked jokingly: "Does my bump look big in this?"

Her friend and former bandmate Cheryl Fernandez-Versini responded with "Not at all", along with shocked emojis.

Walsh, who will welcome her first child in the coming weeks, will be the second Girls Aloud star to become a mother following the birth of Nadine Coyle's daughter earlier this year.
