Lindsey Stirling has admitted that she had her "mind blown" by John Legend.
The violinist shot to fame on America's Got Talent and couldn't quite believe the news when she found out the musical superstar hoped to work with her on a new version of 'All Of Me'.
Speaking exclusively to BANG Showbiz she explained: "John is an incredible artist and such an amazing writer it was pretty mind-blowing when he reached out and asked to do a different version of 'All of Me'. That was pretty awesome."
As well as working with John she's gone on to work with British singing sensation Jessie J on the star's new song 'Loud' from latest album 'Sweet Talker'.
"I love Jessie J, unfortunately she was in London and I was in LA so we couldn't actually meet but I worked with her producer.
"It was really cool because I've always loved Jessie J she's one of my favourite live performers so it was so cool to be able to record her album."
Lindsey's now set to go on tour with Andrea Bocelli and is "so excited" about hitting the road.
"We haven't worked with him yet but we meet him right before we go on tour, I've been learning the music on my own but I'm so excited.
"His camp reached out and invited me to do it and it turned out it was perfect timing with my tour."
Lindsey continues the UK and Ireland tour with Andrea at the following venues:
November 14th - O2 Arena, Dublin
November 18th - Echo Arena, Liverpool
November 20th - The 02, London
November 21st - LG Arena, Birmingham
