A Qantas passenger has made wild claims about comedian Russell Brand, alleging that he “caused a scene” and stormed off a flight headed from Brisbane to Perth after refusing to be sat too close to other passengers.

Eyewitness Jordan Trevis claims the comedian kicked up a stink after being seated next to other folks.

“He gets on and he’s being a bit rude. He was complaining about the plane and how close he had to sit to someone else,” the onlooker told The West Australian.

“He started complaining about the seat and the quality, it wasn’t what he was expecting.”

Trevis alleges Brand got up with his bag, went to the loo, then exited the aircraft after another passenger sat down next to him.

“He was causing a bit of a scene. They [the flight attendants] weren’t too happy with him, he was clearly being a bit rude,” he claimed.

Three flight attendants spoke to Brand, Mr Trevis claimed.

Following the alleged incident, the British comic, who is in town for his comedy tour, Russell Brand: Recovery Live, later cancelled his sold out show in Perth, claiming that an audience member had been diagnosed with coronavirus.

“We have to SADLY CANCEL TONIGHT’S SHOW IN #PERTH because there has been a CONFIRMED CASE OF CORONAVIRUS in someone who attended a recent show and I am not happy with risk for me or for any of you. My apologies, I hope I see you soon.”

He did not, however, address the incident that occurred on the flight from Brisbane to Perth.

He has instead posted the following promo for his podcast Under The Skin:
