Jessica won our Newsround Press Pack competition to go backstage at the Olympic torch concert in London.
In her report she tells us what it was like meeting some very famous faces.
"The day of the Olympic torch concert arrived and I had an exclusive backstage pass.
First we went to a tent where we would be stationed for the rest of the day.
We heard that McFly would be coming for me to interview them soon, so we quickly thought up some questions to ask them.
Then the moment came and I started to ask them questions just as I had rehearsed.
At the end I got all their autographs and said goodbye to them.
I could now relax but was still having to think of questions for the next people who were Emma Bunton, Will Young and Rachel Stevens.
They went OK but then it was time to interview some stars that were famous when my mum was young such as Ronnie Wood and Rod Stewart.
