A WEEK ago cancer patient Chelsea James was looking forward to seeing her pop idol Beyonce perform in concert in Sydney.
Yesterday she was celebrating the fact that "I've had over 700,000 hits on YouTube.
The 11-year-old stole everyone's hearts on Friday night when she was plucked from the audience at Acer Arena to be on stage with Beyonce, The Daily Telegraph reports.
With her wispy hair - some of which is still falling out from her chemotherapy - blowing in the wind, she stood alongside her idol, who dedicated Halo to Chelsea.
It made her and many of the 15,000 concertgoers cry.
"I was breathless", Chelsea said.
The video clip of the tribute has swept around the world, boosting Beyonce's popularity and making the girl from Newcastle an instant star.
Yesterday Chelsea channelled the energy and girl power of Beyonce with a performance of her own at a children's hospital.
Singing her own version of Halo, Chelsea strutted her stuff at the John Hunter Hospital in Newcastle.
I sang a couple of other songs from Beyonce, she said. I've been doing it since I was four.
Just like the real star, Chelsea was swarmed by her fans, who wanted to know what it was like to be on stage with an international pop star.
But had it not been for a kind-hearted stranger who met the little girl at the Ronald McDonald House at Randwick, the memorable moment would never have occurred.
Chelsea won over a volunteer cleaner at the kids' charity house and was offered a gold reserve ticket.
The pop star's management moved Chelsea closer to the stage.
The first I knew of it was at 1am when Chelsea was screaming and crying telling me she had been on stage with Beyonce,said her mother Donna James.
Chelsea's brothers Ryan and Beau and sister Jasmine have been unable to watch the clip as the family has been saving for a computer.
