Union J

In 2012, Shelley was part of British band Only the Young, but left the band to audition for the ninth series of The X Factor as a solo artist singing "Toxic" and was eliminated during the bootcamp stage, as were boy band Triple J. However, due to Rough Copy having to withdraw from the show, an extra spot was opened up in Louis Walsh's category for judges' houses. Triple J's manager, Blair 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 group Times Red.^[8] Union J went on to progress to the live shows and finished fourth, behind Christopher Maloney, Jahméne Douglas and eventual winner James Arthur.

On 3 March 2016, Shelley left the band so he could focus on his acting and broadcasting career.^[9] On 31 January 2022 it was announced Union J would be reforming with Shelley rejoining the band.
