Last night, Justin Bieber’s 3D concert movie ‘Believe’ premiered in L.A., and tons of his family and celebrity friends were there to support him. Big names like Usher, Jaden Smith, Mike Posner, Meagan Good, Kylie Jenner and more all came out, and everyone brought toys to donate to needy children. Check out some pics from the purple carpet in the gallery. ‘Believe’ hits theaters on Christmas day.
