Robbie Williams is hoping for a son. The 'Candy' hitmaker and wife Ayda Field are expecting their second child together and he would love to have a little brother for their daughter Theodora, though he insists another girl would be "cool". He said: "We don't know if it's a boy or a girl but we're going to find out. "If we have a girl, it'll be totally cool but I would quite like a little boy. "Last time I said that as long as it was healthy, I didn't mind. Then we found out we were having a girl and it was a really strange emotion. I was like, 'What am I going to do with a girl?' " The couple intend to find out the sex of the baby in the same way they planned to with their first child, but Robbie admits they will need to be more organised this time around. He explained: "With Teddy, the doctor put the sex into an envelope. We went to dinner and the plan was to open it at the end of dinner... but she forgot the envelope. "I think we're going to do the same thing -- but remember the envelope this time. I don't think we can do it any other way."
