The 'SexyBack' singer says he never gets approached by women now he is dating Cameron Diaz, but claims his fans still try to grab his assets.

Justin said: "I don't get chatted up now. I just get grabbed and groped - it's uncomfortable, but arousing."

Meanwhile, Justin has confessed to taking "too many drugs".

The 'Rock Your Body' singer revealed he has only managed to keep his squeaky-clean image in tact because he gets high in private.

He said: "I've done way too many drugs. I'm just like everyone else, I get completely plastered. I've done my fair share of drugs and I've been caught with my pants down. I just try and make sure there are no cameras around.

"I don't show up drunk to functions and the drugs I do have been in my own private time."
