Lily Allen: Exactly how Lily Allen persuaded Australian police officers to pretend to arrest her is beyond us, but this photo is the result. Shortly after she posted it, someone thought better of it, and the photo was deleted. It's the police officer though, rather than Allen, who is in trouble over this one.
Madonna: This is a photo of Madonna's 13 year old son Rocco and his friends holding bottles of spirits. Since Madonna is from America, a country in which people can buy a rifle 3 years before they can buy a beer, the picture caused something of an outcry. She subsequently told her critics to "get a sense of humor."
Rihanna: When Rihanna turned up at an unauthorised entrance of an Abu Dhabi mosque and embarked on a photo shoot, it wasn't long before she was instructed to leave.
Britney Spears: On the set of the 'Perfume' video shoot, Spears was photographed wearing a sweatshirt emblazoned with 'Virginia Tech', the college at which 32 people were shot dead by a student in 2007. Moments later, she began wielding a fake gun.
Beyonce: Compared to fake arrests, guns and underage drinking, this controversy is fairly tame -but it's Beyonce, so it's 100x worse. The singer posted a tribute photo of herself and the late singer Aaliyah - but she cropped former bandmate Kelly Rowland out of the picture. Later, she posted a beach photo in which Kelly had made the cut - but bandmates Michelle Williams and Farrah Franklin were removed. The slightly egotistical move was picked up on and somewhat criticised.
Nicki Minaj: Though critics praised the music video for 'Lookin' Ass N*gga' for tackling objectification of women, the unofficial artwork Minaj posted, which featured Malcolm X holding a gun, was less welcome. Minaj later apologised for using the photo, but insisted it was a parallel for the way women are treated in hip-hop.
Pharrell: When Pharrell appeared on the cover of Elle wearing a Native American headdress, it was met with outrage from people who saw the picture as "the most disturbing overtly racist, disrespectful co-optation of a cultural object." In Native American society, to be given a headdress is considered the highest honour, and many have likened it to the US Medal of Honor. Later, Pharrell said he was "genuinely sorry" for posing in it.
