Posting on Instagram, Williams sent out a long post explaining his anxieties whilst also making sure to detail his “gratitude” to all his fans.

The 51 year old singer revealed that he had to turn down multiple requests for photos on a recent flight, stating: “This isn’t a complaint, it’s context.”

Speaking of one interaction, the Better Man star said: “One of them handed me a lovely note – kind words about my documentary – and then asked for a photo.

“I wrote a note back. I explained I’d been up since 4:30am, had two hours sleep, and wrangled four kids through the airport. I’ve got bags under my eyes and I’m dealing with anxiety.”

The ‘Rock DJ’ singer shared in the post that this is not only a problem for himself, but perhaps a problem with society as a whole. Speaking of the life and pressures of being a celebrity, Williams said: “There’s a kind of unspoken law: as a celebrity, you should be accessible 24/7.

“Greet all strangers like you’re the mayor of the best town anyone’s ever visited. Make sure their wishes are met, whatever they are. Otherwise – you’re a c*nt. There’s no inbetween.”

He also mentioned that he was sure that half the people he met “couldn’t name one of my albums, let alone say they’ve bought a ticket to my show.

“They’re no more fans than me than they are of the Leaning Tower of Pisa or Big Ben. They’re fans of fame.”

Despite his grievances the ‘Angles’ singer did clarify how much his actual fans mean to him, saying: “If we cross paths in the wild you are a fan of me, I want you to tell me. That means a lot. I’ll make time. I’ve got gratitude for that. It warms my heart when I feel I’ve warmed yours.”

Williams has had well-documented problems with drink and drugs in the past and has been an inspiration to many in the way he’s turned his life around. Although he may come across as a sociable, bubbly creature (a monkey?), he claimed that “Every interaction fills me with discomfort.

“I mask it well. But social interaction still frightens me. So much so, I didn’t go out for years. I had to relearn how to interact. And I had to do it without drugs or drink.”

The former Take That man has seemingly been everywhere in past months, after the release of his biopic ‘Better Man’. He has also had lots to say about the upcoming Oasis reunion, where he was quick to support the Gallagher brothers in the feud about their ticket pricing last year.

More recently, The Lottery Winners revealed that they are working on a new single with Robbie Williams, saying: “We’re working on ideas with him.”

The star has been labelled the UK’s biggest selling female artist following huge online success and racking up 1.7 billion YouTube hits. She is also known for her fun-filled performances and passionate on stage presence, so she says it often comes as a shock to people to find this out.

In an interview with The Sun, Anne-Marie, said: “I have a lot of things going on. I have anxiety, I have obsessive compulsive disorder, I have attention deficit disorder and I have dyslexia. I have a lot of things going on in my brain.”

The performer has been incredibly open about her struggles and how they have impacted her day-to-day life and as a result her career. She said: “I suffer really badly with anxiety. It’s something that affects this career so much because people expect you to be confident.

“You’ve chosen this career, which obviously means you’re very confident because you have to go on stage in front of thousands of people and do all these interviews and meet fans. It’s very odd, because it’s so scary to me, every aspect of this career is scary to me. It got to the point where I couldn’t answer the phone or walk into a room by myself.”

Even though her fan base, the ‘ninjas’, adore the chart-topping solo artist for her honesty and openness surrounding mental health, she still worries about giving off the wrong impression to those who have propelled her to her pop platform. Anne-Marie has admitted that she finds it difficult to keep up appearance and her popstar persona when she is off stage and she often walks into venues, pre-gig, without entertaining floods of her fans.

She continued: “On stage, I am who people think I should be. Then you’re off stage and you meet someone – a fan – and think, ‘oh god, they don’t know me like this. “When I’m walking into a venue and avoiding people, I’m not being a diva. I’m just terrified.”

In the past, Anne-Marie has also opened up about her sexuality on album track Perfect with the lyric: “I’ll love who I want to love, ’cause this love is gender-free”. When quizzed on this, she said: “I feel like for me, I’ve never really even thought about it. I’ve just been attracted to who I’ve been attracted to and I feel like I fall in love with people’s souls more than anything.”

The artist first came into the spotlight in 2015 with single Do It Right, since then she has released numerous chart-toppers including Alarm, Ciao Adios, Clean Bandit’s Rockabye and 2002. Her UK tour, Speak Your Mind, will pop up across 14 locations nationwide beginning May – June 2019. She will also be performing at Soundscape festival this summer, as well as Ise of Wight and Longitude.
