Sophie Washington is one lucky JLS fan. Last week she sang with her heroes as they performed at The Royal Albert Hall.
Her dream came true with the help of the Rays of Sunshine, a charity that grants wishes to seriously ill children.
Sophie told Lorraine this morning she still can't believe it really happened:
The boys were full of praise for her performance:
16-year-old Sophie first got involved with the Rays of Sunshine charity in 2010. She said singing with JLS was the best experience of her life:
Sophie needs a pancreas transplant and is waiting for a suitable donor. The operation will involve her having another pancreas inserted into her body as it is too dangerous to take her malfunctioning one out. She will be the youngest person to undergo the operation in the UK.
Sophie sang with JLS in front of an audience of five thousand people, including a thousand seriously ill children. Other singers to perform at the event include Leona Lewis, Alexandra Burke and Jaz Ellington.
