'The X Factor' rules have been broken by Sam Callahan, for selling merchandise.
The 19-year-old wannabe has set up his own online shop, which sells mugs, keyrings, T-shirts, and even baseball jackets with the heartthrob's name or face emblazoned across it, leading to ITV bosses being angered by the campaign.
A spokesperson for the show told The Sun newspaper: "Whilst in the competition, contestants are restricted from entering into any personal commercial arrangements without prior consent."
One signed photograph, which shows Sam topless with a Union Jack flag draped over his shoulders, costs £12, while a bright pink T-shirt, which reads "Future Mrs Callahan", is £20.
The bubbly Essex lad - who refers to his followers as 'Callafans' - has been busy promoting his new "made to order" goods, which range from £4 to £35, on Twitter.
One tweet read: "You can now buy the sparkly #TeamCallahan T-shirts that my Mum and sister wear every wkend to The X Factor live shows!"
While another said: "If you want one of those T-shirts or some of my other merch. Check out my online shop at samcallahan.co.uk. (sic)."
Meanwhile, fellow contestant Nicholas McDonald, 16, was reportedly barred from using photographs of him from the show makeover on garments, despite wanting to sell them to raise money for a hospital.
