Representing Ireland are Jedward with the song 'Waterline'.
Widely known for their distinctive blond quiffs, the identical twins first appeared on our TV screens as John and Edward on the UK's X Factor in 2009.
Jedward performed in front of an audience of 60,000 people at a concert to welcome US President Barack Obama to IrelandEurovision.tv
Although the boys came sixth, they were crowned the show's real winners and were quickly signed to Louis Walsh's record label.
Jedward's debut single 'Under Pressure (Ice Ice Baby)', featuring Vanilla Ice, was released in 2010.
A year later, the boys won the Irish national selection for the Eurovision Song Contest in 2011, achieving eighth place with their single, 'Lipstick'.
