Penny Lancaster has revealed she is planning to have another child with fiance Rod Stewart - but will wait until after the couple marry next summer.

Rod already has six children from previous relationships but Penny became a mum for the first time last November when she gave birth to their son, Alistair.

In an interview with Sharon Osbourne, Penny revealed they’re planning “a brother or sister” for Alistair after they marry “next summer, June or July.”

She also revealed that despite currently teething Alistair “is so good, an angel, his character is like his daddy’s.”

“Naughty, very funny and he brings a sparkle every time. I can’t wait, if I’ve been out for an evening, to see him.”
