Singer Robbie Williams, who recently turned 40, says he is now at ease with "not being cool".

The Former Take That star, whose career spans nearly three decades, is busy promoting his "Swings Both Ways" album and he feels more relaxed, reports mirror.co.uk.

`I'm far more at ease with not being cool now. Swing is a different kind of cool. I am ready to be a family entertainer, I am not offended by that notion any more," he said.

`Now I am 40, I don't want to be cool anymore, I want to be successful, I want to keep this going as much as I can, health permitting," he added.

The "Feel" singer turned 40 Feb 13.
