Tori Spelling hopes her next baby is a boy.

The former '90210' actress - who already has son Liam, five, and daughters Stella, three, and Hattie, five months, with husband Dean McDermott - says she would like another son to give Liam a play mate.

She said: "We would like a little boy, and Stella ... she's now a middle child and when we told her about the pregnancy she said 'I hope it's a little boy for Liam'.

The 38-year-old discovered she was pregnant whilst being treated in hospital for a migraine just one month after giving birth to Hattie, and admits that while she was shocked, her kids seemed unfazed.

She explained: "It was as if we had said, 'Oh we got milk today'. We brought home milk today and put it in the fridge and you can go help yourself to a glass.'"

However, Dean, 45, has been revelling in his virility since learning of the pregnancy.

Appearing on the Rachael Ray show, she said: "Well, my husband got really lucky that night and then I got lucky. He's feeling real proud of himself.

"He's like a fluffed up chicken. Women walk by and he's like, 'Don't walk too close to me - I've got the batter'."
