Justin Bieber is a good guy: Kylie Jenner

Reality TV star Kylie Jenner insists her close friend and teen pop sensation Justin Bieber is humble and a good guy.

The 16-year-old reality TV star said she does not buy into reports of Bieber's wild behaviour and despite the pop star having a tumultuous year, including complaints from his neighbours and heated arguments with paparazzi photographers, reported Contactmusic.

"He's always been so nice and he's such a good guy despite what everyone says about him. I think he's amazing. He's just been a great friend. He's really cool. He's humble," she said.
