Rapper Nicki Minaj has been accused of acting like a diva during a recent photoshoot.

The Starships hitmaker allegedly arrived a shoot for Billboard magazine in New York in the early hours of the morning, six hours behind schedule, and did not apologise for making staff wait.

A source tells British newspaper The Sun, "Nicki turned up six hours late - everyone had been waiting all night for her... Even then she wasn't apologetic. She just kept falling asleep. It was incredibly rude and everyone was getting really angry with her.''

In October (14), a journalist at America's GQ magazine also criticised Minaj for falling asleep four times during their interview.
