Kimberley Walsh is expecting her second child.

Kimberley, 34, told HELLO! magazine: "We knew soon after we got married that we'd be very happy for baby number two to come along. When I first met Justin 14 years ago, I told him I wanted four children... We're both over the moon.

"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 couple already have 21-month-old son Bobby together and Kimberley says she is more chilled out about her second pregnancy.

She explained: "I feel more chilled during this pregnancy because I know what to expect. When it's your second baby, you don't obsess as much, you become more practical about it and, of course, I've had Bobby to run around after and keep me occupied."

And Kimberley's best friend and Girls Aloud bandmate, Cheryl Fernandez-Versini, is thrilled for the pair.

Kimberley said: "When Cheryl came over to visit, I couldn't keep my pregnancy a secret any longer. She was so happy for us and thinks it's great to keep our family growing and that there will be a small age gap between Bobby and the new baby."
