Kimberley is expecting her first baby with long-term partner Justin Scott and, judging by this new picture, she doesn't have much longer to go!
The Girls Aloud star donned the line green maternity frock earlier today before taking a bump selfie in the mirror.
Sharing the snap on Twitter, Kimberley joked: "Does my bump look big in this?!"
We're pleased to see Kimberley so smiley, because she wasn't feeling particularly well yesterday (20 July).
Although she didn't explain to followers exactly what was up, Kimberley posted a picture of six tearful emoticons on Twitter. Alongside the faces, she said: "Need I say more I have basically a hot water bottle attached to me! Hope you're all enjoying your hot #Sundayfunday."
Since announcing her pregnancy in March, Kimberley hasn't stopped to put her feet up. In recent week, the mum-to-be has been travelling up and down the country promoting her single with Alistair Griffin, 'The Road'.
The song was the official tune of the Tour De France 2014 Grand Départ and last week she and Alistair performed the track live on BBC Radio 2.
