Kimberley Walsh has revealed she is pregnant with her second baby.

The former Girls Aloud star – who is already mum to 21-month-old son Bobby – told Hello! that she and her husband Justin Scott are expecting the pitter-patter of tiny feet once again.

The delighted couple discovered Kimberley, 34, was pregnant not long after they tied the knot in Barbados in January.

She said: “Before I had even taken a test, I knew it instinctively.

“I wasn’t suffering from morning sickness but telltale changes in my body made me certain I was expecting. When I took a home test early one morning to make sure, it confirmed what I’d already sensed. I was thrilled.

“The first thing I did was to wake up Justin and tell him, ‘You’re going to be a daddy again!’”

The singer said her old bandmate Cheryl Fernandez-Versini already knows her baby news, and that Cheryl was “so happy” for them.

Kimberley and Justin said they have decided not to find out the baby’s sex.
