Former Union J star George Shelley has made an emotional tribute to his sister Harriet who died earlier this month.

The 23-year-old former X Factor star was devastated when his sister lost her life after she was involved in a car accident.

Harriet was just 21-years-old when she died after being hit by a car in Bristol.

Taking to Instagram, George shared a throwback photo of himself planting a kiss on his sister’s cheek.

“I will never accept that you're gone. You will always be with me. My best friend, my sister, my angel,” he wrote alongside the post.

“Too pure and too beautiful to walk among humans, you now exist somewhere else, and I am honoured to have had the privilege to spend 21 years with you by my side,” he continued.

“Don't get used to it up there without me, I'll see you soon beautiful girl. I love you Harriet,” George added.

George's former bandmates Jaymi Hensley, JJ Hamblett and Josh Cuthbert also paid tribute to Harriet after she died last week, with Jaymi writing online: “Devastated doesn't even come close! The most beautiful spirit and truly wonderful person! RIP beautiful girl! Love you George and family”.
