Justin Bieber has reportedly landed in a wheelchair after suffering a knee injury in a basketball game, TMZ reports.

While there was some initial confusion as to what Bieber was doing in the wheelchair -- the site originally claimed that it appeared he was using it as a ruse to cut lines at Disneyland -- the singer's camp told the site that he was using the chair to rest after hurting his knee in an earlier basketball game.

The site also reports that Bieber wouldn't even need to use the wheelchair to get ahead of lines at the theme park, since security would privately escort him in and out so he wouldn't get mobbed.

Still, one lucky fan managed to greet a wheelchair-bound Bieber at the Happiest Place on Earth and taped the sweet interaction, which shows the pop star being nothing but gracious as he slowly wheels away.

"Thank you for keeping me strong. I love you," the off-camera fan tells the singer, who then smiles broadly and replies, "Bye, sweetie," as he leaves.
