JLS have been topping the charts ever since they came second to Alexandra Burke in the X Factor in 2008.
Their first album, called JLS, stormed the charts and their first single, Beat Again, also shot straight to number one.
In 2010, they won TWO Brit Awards for their contribution to British music and seemed pretty chuffed to have won!
They've also scooped up two MOBO awards for the best album and best UK act.
The boys have done lots for charity too - here they're wearing silly socks for Sport Relief. Aston has also done a lot of work with anti-bullying charities.
And they topped the charts in 2010 with the official single for Children in Need, Love You More.
In fact, 2010 was a busy year for the band. The boys performed at Radio 1's Big Weekend in Bangor to a massive crowd of fans!
The guys' second album Outta This World went straight to number two in the charts.
