Speaking to E Online, the 'Baby' singer said that he feels it is natural for his supporters to be interested in the details of his personal life.
"I do get it," he said. "My fans are really supportive and amazing and I understand where they're coming from."
Bieber also took time to promote his upcoming 3D documentary Never Say Never, adding: "It's not just a concert film. We wanted to make it like a story, my journey this far. I really wanted to show that to the audience and have them come out with something."
Never Say Never opens in the US on February 11 and in the UK on February 18.
