She continues: ‘He’s a little bit too young to fully understand, but he knows there’s a baby in my tummy.

‘He pretends it’s kicking him! He loves babies in general so hopefully he’ll enjoy helping me take care of him or her.’

How cute?! So… do Kimberley and Justin know whether they’re expecting a boy or girl?

Kimberley says: ‘We want the surprise. I don’t have a preference – I think it would be lovely for Bobby to have a little brother so close in age but I’d also love to have a daughter, so I can’t really lose!’
