Robbie Williams has a private jet on standby as he plays a sell-out concert in case his pregnant wife goes into labour.

“I don’t think she’s going to come today, I think it’s going to be more likely next week,” said Robbie.”But there’s a plane on standby and if I get that phone call I’ve got to go.”

The singer’s also hinted the closely-guarded name of his first child, due any day, will be an old-fashioned one.

“There’s no mad celebrity baby name,” said Robbie.”It’s a very steadfast old school name.”

The 38-year-old’s performing to a packed O2 Arena in Dublin tonight in a special charity concert.
