I need to step up and own actions: Justin Bieber

London: Pop senastion Justin Bieber has apologised after a second video of him making racist jokes emerged online and claims he needs to `step up and own` his actions.

The 20-year-old singer said he needs to `take responsibility` for new footage, filmed when he was 14, reportedly.

"At the end of the day I just need to step up and own what I did. Facing my mistakes from years ago has been one of the hardest things I`ve ever dealt with. But I feel now that I need to take responsibility for those mistakes and not let them linger," he said.

The star`s latest apology comes just days after he was forced to say sorry when another video of him telling a racist joke was published online.
