Julia Carlile the 15 year-old dancer, who captured the viewers heart when she performed with her dance troupe MerseyGirls on Britain's Got Talent, revealed that Simon Cowell approached her backstage and told her he would foot the £175,000 bill for her operation.
Julie suffers from the painful condition scoliosis, a curvature of the spine, that has left her suffering in severe pain.
The procedure which will take place in the States called vertebral body tethering where screws are fixed along a cord inside her back.
It takes just 6 weeks to recover compared to 6 months and is reversible if it doesn't work.
Julia revealed for the first time today that Simon will fund the surgery.
Julia said: "Simon came and spoke to us back stage. Just walking off stage and he said he was paying for it and I couldn't believe it.
"Annie came up to me and said Simon wants to speak to us. "He said we did a really good performance."

"It was quite sad. I'm not going to see any of the girls now before my surgery. We were all crying and saying bye to each other, hugging and crying. we are really, really close friends.
"I'm beyond happy and it means we can carry on dancing together for the rest of our lives.
"He didn't have to do it and he has changed my life. There are no word to thank him for how grateful we are.
It's just unbelievable. "It does not feel real."
Good luck to Julia who flies out to America this week for her operation.
