Justin Bieber is ''keeping it positive'' after Orlando Bloom reportedly tried to hit him.

The 20-year-old singer took to his Twitter account after Orlando attempted to punch him at Cipriani restaurant in Ibiza in the early hours of Wednesday (30.07.14) morning and wrote: ''Keeping it positive.''

TMZ obtained video footage of the incident in which Justin can be heard shouting: ''What's up b***h?''

TMZ also reported that after the incident, Justin left the venue as other guests at the party started applauding the English actor.

As well as Orlando and Justin, other stars at the party at Cipriani included Paris Hilton and P. Diddy.

It is unknown why the pair started fighting, but Bieber has been linked to Orlando's model ex-wife, Miranda Kerr - the mother of his three-year-old son Flynn who he split from last October - in the past. The pair were even spotted partying together after a Victoria's Secret fashion show in 2012.

After the alleged punching incident, Justin posted - and then quickly deleted - a photo of Miranda on his Instagram account; the biggest indication yet that the feud was caused by his rumoured relationship with the brunette beauty.
