Robbie Williams is less sexual these days.

The 40-year-old British singer is known for his piercing blue eyes, seductive dance moves and amazing voice.

However, he says his days of playing up to that image are almost behind him.

"I'm less sexual I suppose," he mused to "But that's probably to do with the fact that I'm older as well. Less gyrating and sexual innuendos."

Robbie and his wife Ayda Field already have 20-month-old daughter Theodora together, and in April he announced they are expecting their second child. He would be pleased to show his kids the ropes, should they want to follow in their famous father's footsteps.

"It's a lot of fun showbiz, and I would be able to help them to navigate it," he said.

"It's a lot more fun than a normal job, but I'm only happy if they're happy."

Even though he's not worried about the prospect of his brood eventually wanting a life in the limelight, he's keen for it not to happen too soon.

"I don't want them to be a child actor or a child model," he grimaced. "Nothing in public; that lens kind of warps everything. I would like them to be as normal as possible, for as long as possible."

The star has admitted to drug taking in the past and revealed he still occasionally has cannabis. However, fatherhood has significantly calmed him down.

“Since the birth of Theo I’ve become less reckless,” he said in a past interview with British newspaper The Mirror. “I last drank 13 years ago, the last time I got high was two days ago. No big drug sessions, mind, just a small amount, purely to relax.”
