Back when this celebrity couple were loved-up and still together in 2008, they were spotted frolicking in a bed on a 12-hour flight from Los Angeles to London. Sienna and Rhys's shameless PDA was reported in the Daily Mirror. They were reportedly seen kissing and play-fighting in the Upper Class cabin. Passengers then watched as Rhys pulled off his top and jumped into Sienna's single, 33-inch bed before they watched a film, ate dinner and Rhys went back to his own seat... aah, how romantic.

In February 2011, former Westlife singer Brian McFadden was marched off a Virgin flight from Los Angeles to Australia, allegedly for lighting up a cigarette and being under the influence of alcohol. He denied being drunk, despite fellow passengers claiming he drank heavily, shouted and was being abusive to everyone around him before he was restrained by Australian TV presenter Kyle Sandilands. Australian Federal Police confirmed that they were asked by Virgin to meet the flight on its arrival – but as there was no formal complaint made by the airline, and the singer was interviewed and released without charge. He later tweeted: 'Wasn't arrested! Didn't smoke on the flight. And the Virgin staff were very nice. I did have a few drinks but I was not smashed and abusive. If reports were true then I would have been arrested, fined and wosrt (sic)! Banned from my favourite airline V Australia. Storm in a tea cup.'

Police went on board and spoke to Love in the Upper Class cabin. She was taken to the airport's police station and later released with a caution for causing harassment, alarm and distress. As she left Love said: 'I cussed at a lady - my daughter always said I had a potty mouth.'

Being told off is something most teenagers are used to but when Justin Bieber was labelled a "security risk" by a Qantas flight attendant in May 2011 for acting like a child, it wasn't the reception the star usually receives. According to reports in the Daily Telegraph, Bieber was said to have left his seat in business class on a flight from Sydney to Melbourne and decided to go for a walk as the plane was taxiing. The flight attendant ordered him and his bodyguard to sit down and told him that he'd be treated like a child if he acted like one. He later apologised after she told him to respect her workplace.

Singer Whitney Houston was almost kicked off a Delta Airlines flight in October 2011 when (in true diva style) she refused to buckle her seatbelt before the plane took off in Atlanta, Georgia. After being warned that she would have to leave the flight, the singer eventually allowed a flight attendant to do it for her and the plane was cleared for take-off. Phew!

Oasis singer Liam Gallagher was famously banned for life by one airline for his behaviour.  Cathay Pacific made the drastic move after he allegedly abused crew and passengers on a flight to Australia back in 1998. Passengers complained that Gallagher smoked, swore and threw objects at them and staff on the flight from Hong Kong to Perth. In 2001, Gallagher was again in trouble with an airline when he reportedly humiliated a member of British Airways staff at Gatwick Airport by touching her bum, prompting a police investigation.... 

The singer allegedly once kicked off at her niece in an air rage rant after her flight taking her from Tokyo to Scotland was delayed. In another incident, she had a mid-air meltdown on a night flight from LA after pulling out of America's Got Talent and was singing and crying during the flight, stopping other passengers from sleeping. Most recently in November 2011, Susan Boyle reportedly spent most of a 26-hour flight to Australia crying and arguing with her crew. Business class passengers complained about her behaviour during what was her first journey trip to Australia.

In 2006, TV legend David Hasselhoff was allegedly banned from a British Airways flight for being drunk. The Baywatch star was due to fly to Los Angeles from Heathrow but was said to have been staggering around, mumbling to people and even tried to pick up a shop worker at Heathrow Airport. He reportedly downed bottles of beer and shots of whisky as he waited for his flight and told BA staff he was upset about divorcing his wife of 16 years. Hasselhoff wasn't aggressive and when he was told he couldn't board the plane, agreed with the staff.

French actor Gerard Depardieu made the headlines in August 2011 when he was removed from a CityJet flight from Paris to Dublin for urinating on the plane. The aircraft was still on the ground and preparing for take-off when Depardieu asked to use the toilet but was told by staff to stay in his seat. He was then said to have stood up and took to the aisle to pee in a bottle. He later said that he had been desperate to go to the toilet after drinking a litre of water before boarding the plane. He offered to clean up any mess but was still thrown off of the flight!

In Decmber 2011, actor Alec Baldwin was kicked off a plane for using his mobile phone before his American Airlines flight took off. The star of 30 Rock complained on Twitter that an attendant had "reamed me out" for playing a game on his mobile phone, sparking a huge furore between the actor and the airline. American Airlines said he had been loud and abusive, while Baldwin claimed all he had been doing was playing the game Words With Friends. The saga continued when he appeared on US TV show Saturday Night Live dressed as an AA pilot and made a spoof apology, airline flight attendants. 

In 2008, Naomi Campbell was banned from flying with British Airways over a row about her lost luggage. The supermodel, known for her fiery temper, flew into a rage when one of her bags wasn't put on the Los Angeles-bound flight. She reportedly swore at the captain and ordered him to bring her her bags. Campbell was asked to leave the flight but refused and three police officers arrived to remove her. After a violent struggle, she was handcuffed and marched off the plane by police and later released on bail after spending several hours at the police station. Getting between a fashionista and her bags? That was never going to end well!
