Justin Bieber has slammed allegations claiming he "acted like a brat" on an American Airlines flight.
Earlier this week, Fox 411 reported that the Somebody To Love hitmaker was badly behaved on a flight from Los Angeles to Asia, even refusing to take his seat when the aircraft was preparing to take off.
A source revealed: "He then gave the staff a really hard time the whole flight, nobody could believe it,"
They added: "And then at the end, the captain introduced himself to Justin and kindly asked for an autograph, and he rudely refused."
Despite these reports, the Biebster has denied the incident happened telling TMZ: "I have no clue. I have never heard that rumour. I don't think you should believe everything you hear. People make up stuff all the time."
The 17-year old has previously been accused of misbehaving on a flight from Sydney to Melbourne back in May, where an air-hostess said he was "acting like a child."
