Meet The Wanted! The new boy band has just spent a week at number one with their hit single All Time Low.
From left to right they're called Jay, Max, Tom, Nathan and Siva.
They were formed in 2009 after a mass audition - a bit like the X Factor, but without the TV cameras.
Here they are making up our very own Newsround song!
Jay, Tom and Nathan got into the band during the first load of auditions, and Max and Siva came in during the second lot.
They all live together in a house in London... What do you reckon they play on their sound system? JLS?!
Time for the boys to relax after a long afternoon chatting to Newsround!
