The Smile star, who has always been vocal with her criticism of the British government, blamed U.K. officials for keeping refugees out during a recent chat with a 13-year-old Afghan boy at a migrant camp in Calais, France.

After the teen explained how he had ended up in the camp, dubbed The Jungle, having fled the Taliban, Lily told him: "I apologise on behalf of my country for what we've put you through."

The offhand comment caused an instant backlash, with many individuals, including politicians, slamming her sentiment.

Lily wasn't the only celebrity to face heavy criticism for her thoughts about the migrant issue. Retired England soccer star-turned-sports presenter Gary Lineker also came under attack after sharing a tweet in which he stated: "the treatment by some towards these young refugees is hideously racist and utterly heartless".

His remark led editors at one British newspaper to call on BBC TV bosses to fire him from his role as host of football programme Match of the Day.

Lily has now addressed their brutal media treatment in an essay written for Vice magazine, in which she accuses the press of trying to scare celebrities into silence when it comes to politically-sensitive issues.

"The press are willing to slur the reputation of refugees, to 'monster' celebrities who disagree with them by bringing up negative stories from their past until they back down..." she argued. "Some people will say, 'You're just a pop star - you should just make music.' But 40 years ago, even 25 years ago, you couldn't really be taken seriously as a musician unless you had a political stance. The mainstream media saw that threat coming - that stars could wield a lot of power - so they monster people like me to put them off getting involved."

Lily frequently hits headlines with her opinionated views, which she regularly shares on social media. However, she did her utmost to explain in the Vice essay why she had opted to visit The Jungle with the help of organisation officials at Help Refugees UK.

"I went to Calais because I wanted to do what I can to help," she wrote. "I wanted to try to remind people of the humanity at the heart of the crisis, at a time when refugees were being demonised in the press.

"But after the film of my trip aired I found myself caught in a familiar constellation of tabloid and social media aggressors. It began on Twitter, with near-universal negative comments... There was a real hate in the things people wrote, as if me going to Calais was a vindictive attack on our country.

"I didn't think going to Calais was particularly controversial, but it turns out that saying we need to help vulnerable children is now dodgy territory... Some of the anger felt familiar. People thought it was wrong for someone who has money to moralise on behalf of everyone else."
