Bieber: Love should come before sex

Justin Bieber has opened up to Rolling Stone magazine about his views on love and sex.

The Canadian singer - who turned 18 in March - is pictured on the cover of the iconic music magazine in a tight white vest with the caption "Justin Bieber - Hot, Ready, Legal".

Justin - who is dating fellow teen star Selena Gomez - told the magazine: "I don't think you should have sex with anyone unless you love them."

Asked about waiting until marriage he said: "I think you should just wait for the person you're... in love with."

The Boyfriend singer also revealed he would never think of becoming an American citizen.

He joked: "You guys are evil. Canada's the best country in the world."

Justin added: "We go to the doctor and we don't need to worry about paying him, but here, your whole life, you're broke because of medical bills.

"My bodyguard's baby was premature, and now he has to pay for it. In Canada, if your baby's premature, he stays in the hospital as long as he needs to, and then you go home."
