Music fans will get a treat at the end of June when loads of top stars perform at a free concert in London.
McFly, Jamelia and Will Young are some of the pop acts on the bill, with older stars like Ozzy Osbourne and Rod Stewart also singing for free.
Around 70,000 people are expected for the concert on 26 June, and they'll have to apply for free tickets.
The concert is to celebrate the arrival of the Olympic flame in the UK on its way to Athens for the Games in August.
