In May 2012, after eight months together, Triple J and soloist George Shelley both auditioned in London for the ninth series of The X Factor. Triple J performed Rihanna's international hit "We Found Love", whilst George covered an acoustic version of Britney Spears' "Toxic" – in which he also incorporated his guitar. Both acts progressed to the next stage of the competition, receiving positive critique from all judges present. Bootcamp saw Shelley perform Labrinth's "Earthquake", competing against female contestants; Charlie Cammish and Meg O'Neill. Triple J first sang Maroon 5's "Moves Like Jagger", before contending for the final place at judges' houses with GMD3 (later District3). They covered Chris Brown's "Yeah 3x", but were sent home after GMD3 were eventually chosen for judges' houses. However, following Rough Copy's forced withdrawal from the show, Dreelan was contacted by The X Factor producers with an offer for the group to return, on the basis that Shelley was added to the three-piece. All parties accepted the offer and the band – now a four-piece – became Union J and advanced to judges' houses alongside fellow recalled Times Red.
