Star singer Pixie Lott turned the House of Commons from a place of politics into a place of pop when she played a special gig there.
The concert was put on to help promote a charity Pixie supports, called CRY.
CRY helps raise awareness about heart conditions in young people.
Press Packer Tom was lucky enough to be there and got all the gossip from Pixie on The X Factor and scary Simon Cowell!
