'Dad-Sized' But Happy - Robbie Williams Says Fatherhood Has Made Him Content

Robbie Williams says he is 'dad-sized' but happy

Robbie Williams has admitted in an interview that as his milestone 40th birthday approaches, parts of him have turned a bit 'dad-sized' - but he says he couldn't be happier with life.

The Take That star spoke to The Sun just after he performed the Dublin leg of his solo Take the Crown world tour, and credited his wife Ayda and baby daughter Theodora with his renewed zest for life.

After his well-documented battles with alcohol and drug problems in the past, Robbie told the paper that these days, he is 'just so content and so happy thanks to my wife and thanks to my daughter'.

"I want to go and play. I want to go and enjoy myself with people enjoying me," he said. "I want to play with the fans and all the people who have been dragged along to see this 'thing'."

The doting dad - who dedicated the track 'Come Undone' to his baby daughter, Theodora Rose - said that nothing matters to him now more than his family.

"I am honestly the happiest I've ever been. Being a dad, having a daughter, it's just the most important thing in the world to me," he said. "It has changed my life and that's not being dramatic, that's the way it is. Suddenly it all makes sense."

Robbie and his wife Ayda welcomed little Theodora Rose into the world last September.
