Robbie Williams has confessed he is feeling both "overjoyed and terrified" at the prospect of becoming a dad.
The Take That singer has been training with stars including Olly Murs and Aston Merrygold and Marvin Humes from JLS ahead of Soccer Aid 2012 on Sunday, a celebrity charity football match in aid of Unicef.
Robbie said of his impending fatherhood: "I have been genuinely overjoyed and terrified and then going back between the two on a daily basis and today I'm overjoyed and I can't wait.
"I know the sex of the baby and I'm very, very excited. I can't tell you, the Mrs is like 'Don't go telling' and I said I won't."
He added: "It's a girl. I'm very, very excited about becoming a daddy, I can't wait."
The singer and wife Ayda Field announced in March that they are expecting their first child.
Robbie will captain the England team as they take on The Rest Of The World, captained by Twilight star Michael Sheen and including Will Ferrell and Fight Club actor Edward Norton. The match on Sunday at Old Trafford in Manchester will be broadcast live on ITV1.
The 38-year-old confessed he hadn't trained as much as he would normally, but said he was still confident of taking back the trophy from The Rest Of The World, who won on penalties last year.
Robbie said of his preparations: "I've been ill, so I haven't been able to train but normally it's a good three months before."
