Rylan Clark and JJ Hamblett from X Factor boy band Union J have been teasing fans with a steamy naked photo.

Clark accompanied the image with the caption: “Sorry girls…. Me and JJ @unionjworld have something to tell you ….. X.”

However, he later clarified that he had just been joking around with Hamblett who is straight.

Union J star Jaymi Hensley followed the advice of his X Factor mentor Louis Walsh and revealed that he is gay and had been in a three-year-long relationship with his boyfriend last November.

Clark, who rose to fame in 2012 on the reality music show and won this year’s Celebrity Big Brother in January is gunning for Olly Murs’ presenting job on The Xtra Factor – although there is currently no vacancy.

Clark told Now! magazine: “Olly and Caroline are genuine mates and since I’ve been on the show, Caroline and I have become really close. We go out together and have become great friends, so we have that chemistry too. I love her to bits and it would be great to work with her.”

The 24-year-old has also posed naked for the March issue of Cosmopolitan to raise awareness of male cancer for Everyman.

He said: “I did a good bit of prep for the shoot, making sure everything was trim and proper. I even had a little shave of the nipples! It’s important to look after yourself on the inside as much as on the outside.”
