The Australian girl who became a YouTube sensation after music superstar Beyonce called her on stage to sing Halo has died following a decade long battle with cancer.
Chelsea Lee James from Newcastle, North of Sydney, died on Monday night, just three months shy of her 16th birthday.
Her Aunt, Lisa Sams, confirmed her death to News Corp Australia on Tuesday.
She says Chelsea enjoyed a special Easter Sunday with her mum at the Crowne Plaza before her condition deteriorated and she was rushed to John Hunter Children's hospital on Monday.
Chelsea became a internet sensation in 2009 when Beyonce invited her on stage during her concert at Sydney Acer Arena.
There wasn't a dry eye in the arena when the pair sang the hit song Halo to close the concert.
"It was amazing. It was breathtaking actually ... I couldn't say a word I was just breathless, Chelsea told the Nine Network the day after the concert.
"I wasn't expecting it to happen. I don't no how she picked me out of the crowd.
"It was just like nothing else mattered in the world it was just me there with Beyonce," she said.
