Steve Jones has been nursing a secret injury since launching America's X Factor last month.
The Welshman broke a rib partying too hard after a Beyonce show.
The Welshman took on hosting duties of upcoming TV special A Night With Beyonce, and he toasted the programme with a boozy night out after the recording in July.
But Jones hurt his rib during the celebrations - and he concealed the injury so he could carry on promotional duties for Simon Cowell's latest reality TV venture.
He tells Glamour magazine: "I broke my rib... when I went back to London to host an evening with Beyonce, and got so drunk that I fell over."
