Now it appears that the finalists are set to break more hearts, as they also debuted a mature look on the cover of the track.
The black and white shoot sees members JJ Hamblett and Josh Cuthbert take on a smouldering stance whilst Jaymi Hensley and fan favourite George Shelley opt for a cheeky grin.
Fan favourites: The boys were a hit with the ladies when attending the Jog On to Cancer Party in London earlier this month
Looking
fashionable in leather and tailored blazers, the sexy shoot is sure to
be a hit with their female fans who have already amounted to 900,000 on
Twitter. Whilst the show's fans have to wait a while longer to hear any material from winner James Arthur, the boys have been quick to the post and the single will drop as early as June 2nd.
The band have teamed up with a group of producers responsible for making tracks for the likes of boy band royalty such as Westlife and more recently One Direction.

the perks of the success! Union J can't keep the girls away as they are
mobbed outside the Jog Onto Cancer event earlier this month
The
band said: 'We’ve been through a lot in the short time we’ve been
together and this song sums up how important it was for us to be there
for each other.'If you’d have told us at the beginning of the X Factor auditions that we’d have a record deal and would be releasing a single we wouldn’t have believed you.
'We’re so excited to release Carry You and hope everyone likes it as much as we do. Everyone can relate to the track.'
The new single comes after the band were mobbed by a group of girls at the Jog On To Cancer event recently, in a sight reminiscent of their pop counterparts One Direction.

'To be honest with you we are quite bad with chat up lines. We are like four geeks,’ said 19-year-old singer George Shelley.
‘I don’t think we are ever going to get used to it to be honest. We go back to our normal lives every night and then when we wake up in the morning there is this lifestyle with all these girls. It’s weird, we’re just normal guys.’
Nail biting moment: Union J lost out on a place in the X Factor final last year to Jahmene Douglas
'The
girls has built up somehow, I’m not too sure how. There’s always girls
outside. We thought everyone was going to forget us, normally there’s a
calm before the storm after X Factor before you release a single.’The boys are the latest amongst a string of acts to have penned recording contracts with X Factor boss Simon Cowell at Sony.
Ella Henderson and Jahmene Douglas were amongst the other contestants who also signed deals along with winner James Arthur.
