The account, which shares the inspiring messages which are written on London Underground information boards, created a special version just for Sarah this week.
The board reads: ‘From attending seven schools to winning a Brit award, reaching number one in the charts.
‘Appearing on television and acting on the silver screen; achieving above and beyond anything a little girl could dream of, then waking up in a nightmare with a cancer diagnosis and having to get used to a new way of life and a whole new routine.
‘You’re so much more than a rock chick, a caricature, a high street honey, a party animal and a blonde bombshell.’
The message continued that ‘celebrities can still go through dark times and hell’ despite the glamorous lives they lead.
It concluded: ‘You’re an inspiration and your fans will stand by you without a doubt; nobody can rewrite a whole lotta history, but, it’s never too late to remind people of the other side of you and set any twisted headline or record straight.
‘We love both sides of you and we will always be there to hear you out.’
The account added: ‘This is for the one and only Sarah Harding. Thanks for being you, being an inspiration and writing such an incredible book. We will stand by you.’
Sarah recently shared details of her cancer battle in her memoir Hear Me Out and has also released a surprise single, Wear It Like A Crown, proceeds of which will go to The Christie NHS Foundation where she is receiving treatment.
The track was a previously unreleased song Sarah found while looking for photos for the autobiography on her old laptop.
She said of the song: ‘I’ve always really loved it, and it made me feel a bit sad that no one ever got to hear it.
‘I mentioned this to my team and they said we could release it, and I thought “why the hell not?”’
Sarah had revealed that she was living with breast cancer in August, which has spread to other parts of her body, and said in her autobiography that she may not see another Christmas.
