Penny reveals the couple want another child after they've wed

Rod Stewart and Penny Lancaster are so delighted with their nine-month-old son Alistair they’re already planning a second child.

Penny, 35, confided in Sharon Osbourne about her desire for a bigger family when she appeared on her new show yesterday.

The former model is planning to marry Rod, 61, next summer and added: ‘Yes, we plan a brother or sister after the marriage.’

She described Alistair as very like his father and said: ‘He’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.’
