It's all because he had been invited to audition for the show by a talent agency.
So is it all a fake, a fix and a set up?
Firstly, all of those who appear on the show have been 'invited' to audition, whether it be via a mass casting call by hosts Ant and Dec on TV or a more 'personal' invite, such as via Twitter in the case of Craig.
Next, being personally invited doesn't get you any further ahead of other hopefuls with the same audition process for all acts. A spokesperson confirmed: "BGT does encourage acts to apply but any such acts are required to audition on the same basis as any other applicant and normal programme rules apply."
Of course the implication of such stories is that those who have been personally asked to audition may have their spot in the next round already secured or get an unfair advantage but it's simply not true.
Many acts who are cast for the show's try outs don't even make it before the judges and those that do - such as recent ventriloquist Tony Baloney - can find themselves getting buzzed off by the panel.
It's clear there's no fix and unfortunately all these claims do is take away from the talent of perfectly legitimate acts who we may have never seen otherwise.
