Kind hearted Florence Welch stopped by a hospice to give a private performance to a cancer stricken teenager who missed one of her concerts.

The 29-year-old British pop star held the hand of 15-year-old cancer patient Karinya Chen as she sang Shake It Out and Dog Days Are Over backed by bandmate Rob Ackroyd on guitar.

The sweet moment came as Welch, who performs as Florence And The Machine, stopped by Hospice Austin's Christopher House in Texas on Friday.

Karinya's mother, Jennifer took to Instagram to express her gratitude towards Welch, writing, '@florence of #Florence&TheMachine is such a beautiful and kind soul!. She brought so much joy to all of us today. What a blessing!'

She carried on her praise in a second post, writing, 'Florence is not only an awesome artist but an even more amazing human being! She made my sweet pear so happy today.'

In harmony: Florence + The Machine gave the patient their undivided attention

Making her day: Florence Welch held the hand of the 15-year-old patient at Hospice Austin's Christopher House on Friday as she and the girl sang Shake It Out and Dog Days Are Over while backed by the frontwoman's bandmate Rob Ackroyd on guitar

Hospice Austin shared cell phone footage of the surprise show on YouTube, and wrote: 'Today we were privileged to witness the clear joy of a room full of teenagers singing with Florence Welch and guitarist Rob Ackroyd from Florence and The Machine.'

And they explained that the singer: 'came to Hospice Austin's Christopher House to give a private concert to a teen who missed her concert last night due to her illness.'

According to Christie Kramer, a nurse practitioner at Hospice Austin, the coming together was a joint venture by Florence and the hospital.

'We have a patient who held long cherished tickets to see Florence And The Machine last night with her BFF. All week through set back after set back she asked if she would be able to go.

'We tried to entertain the idea and it felt so scary and overwhelming for the medical staff and her mother that finally I said no, and my hear broke again.'

However, Kramer then told People magazine, 'through a remarkable effort on the part of 'Christopher House and Hospice Austin Staff, we were able to make contact with Florence. My patient's mom was so nervous- will she really come? Is she here yet? She kept popping out of the room and checking.

'And Florence came. And her mom burst into tears of joy at the sight of her and Florence gave her a big hug. '

'The room was full; full of joy and warmth and love and life and singing. Thank you, Florence!'

One of the patient's friends also took to social media to thank the group for their kind gesture.
