Jon Bon Jovi admits there is always "temptation" to cheat on his wife.

The 'Always' hitmaker - who has children Stephanie, 19, Jesse James, 18, Jacob, 11, and Romeo, nine, with wife Dorothea - insists he is not a "perfect" husband, but he isn't interested in sleeping with anyone behind his spouse of 24 years' back.

He said: "I have a wife who I adore, without her the cards would crumble. Every day there's temptation. I don't go looking for it either. Am I perfect? No. But do I aspire to finding a mistress somewhere? I really don't."

Last November, Stephanie was found unconscious in her university dorm following a heroin overdose and the 51-year-old singer believes her plight to be more common than people realise because her generation are under so much "pressure".

He added in an interview with the Daily Mirror newspaper: "There's a lot of pressure on this generation. They have a lot easier access to things than yours or my generation had.

"She was by no means sticking needles in her arms. But there's a lot of synthetic stuff in the world and a lot of temptation and access and pressures that just a generation ago you and I didn't know about.

"I wasn't aware of it, not because I'm not home but because it is a different world. Our world is far more relatable to our parents' world than the kids' world.

"There's many more pressures on kids - what is this college degree going to do for me, what am I going to be when I grow up, will I be able to accomplish things?"

And despite his rock star lifestyle, the Bon Jovi singer insists he has never taken drugs.

He said: "I never did a thing. I didn't even do anything that could open the cover of the book. I was never attracted to it."
