TORONTO - Rolling Stone magazine has amended controversial comments Justin Bieber made about abortion for a cover story due out Friday.

In the article, Bieber was asked if abortion is acceptable in cases of rape.

In initial excerpts posted on the Rolling Stone website, Bieber was quoted as saying: "Um. Well, I think that's really sad, but everything happens for a reason. I guess I haven't been in that position, so I wouldn't be able to judge that."

On Thursday, Rolling Stone said it had made an editing error that included an incomplete quote from the teen star.

On its website, the magazine said the full quote was: "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."

Rolling Stone reporter Vanessa Grigoriadis, who came under fire in some quarters for asking the teen about abortion in the first place, defended her line of questioning Thursday on Twitter.

"A 16 year old kid, to be 17 in a couple weeks, who has control over a large population should be asked all questions," she tweeted.

Grigoriadis attempted to interpret Bieber's comments in an interview with gossip site PopEater.

"I think he meant that God has a plan," she told PopEater.

"Even for the most die-hard Christian, it's hard to justify rape as part of God's plan, and harder to justify rape that leads to pregnancy and abortion. I think he was wrestling with that in his answer, which I found to be solid and logical. I think it is being widely misunderstood. He did not say that rape was part of God's plan."

The Stratford, Ont.-raised Bieber also told Rolling Stone that he'll never become a U.S. citizen because he cherishes Canada's health-care system.

He also weighed in on sex, saying he believes people should hold off until they are in love.

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 a big success at the box office.
