The mighty Westlife took to the X Factor stage at Wembley Arena during tonight’s live final to perform for the last time on the show.
The boys, who announced earlier this year that they were splitting up, sang their single What About Now, showing just why they have become one of the biggest boy bands on the planet.
Dressed in smart black outfits, Kian Egan, Shane Filan, Nicky Byrne and Mark Feehily belted out the soulful track amid screams from the girls in the crowd.
The boys, who have been together for 14 years, are the only act in British and Irish history to have their first seven singles peak at number one in the charts.
Westlife have sold over 44 million records worldwide and have accumulated 14 number one singles in the UK, the third highest in UK history.
They have also broken numerous records and have been credited as the second biggest-selling artist and biggest-selling band of the decade by The Official Charts Company.
The band performed their classic hit Flying Without Wings on The X Factor in 2008 alongside JLS and returned in 2010 to perform new single Safe.
Kian was also a guest judge on the show when he joined Louis Walsh at the Judges Houses stage of the competition in 2007.
The group have recently released a Greatest Hits album and will disband in 2012.
