Canuck heartthrob Justin Bieber has told Rolling Stone magazine that he'll never become a U.S. citizen, because he cherishes Canada's health-care system.

"You guys are evil," he laughingly told the magazine in a cover story that hits stands Friday.

"Canada's the best country in the world. 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."

The 16-year-old appears on the cover of Rolling Stone wearing a white undershirt and silver chain under a black leather jacket that has slipped down on one shoulder.

'Biebs' on sex

In the story, Bieber also offers his views on sex.

"I don't think you should have sex with anyone unless you love them," he told the magazine.

Asked if he believed in abstinence before marriage, Bieber said: "I think you should just wait for the person you're … in love with."

The Baby singer is reportedly dating teen star Selena Gomez.

Rolling Stone reporter Vanessa Grigoriadis also asked Bieber about his stance on abortion.

"I really don't believe in abortion," he told the magazine. "It's like killing a baby?"

When asked if it was acceptable in cases of rape, he told Rolling Stone: "Um. Well, I think that's really sad, but everything happens for a reason. I don't know how that would be a reason. I guess I haven't been in that position, so I wouldn't be able to judge that."

'Biebs' on politics

Although he isn't yet old enough to vote, the mop-topped teen also weighed in on politics.

"I'm not sure about the parties," Bieber told Rolling Stone. "But whatever they have in Korea, that's bad."

Bieber's comments about the U.S. health-care system prompted an immediate online reaction.

'Bieber says American health care system is evil, prefers Canadian plan. People three times his age aren't that smart'—Tweet from film critic Roger Ebert

Some commenters on the Rolling Stone website chastised the teen, saying he didn't know what he was talking about. The Huffington Post and the Drudge Report also picked up Bieber's comments.

Film critic Roger Ebert lauded the singer on Twitter.

"Bieber says American health care system is evil, prefers Canadian plan," Ebert tweeted. "People three times his age aren't that smart."

Bieber was shut out at Sunday's Grammy Awards, but won a Brit Award on Tuesday for international breakthrough act award.

His new movie Never Say Never has been burning up the box office.
