Both The Sun and The Mirror allege that the musical trio - Sonny Jay, Te Eugene, Eddie Brett - skipped early pre-filming audition rounds after being approached to apply for the show by producers.
Got Talent representatives have denied the reports, insisting that the recruitment of Loveable Rogues to appear on the show was standard procedure for the ITV1 talent show.
"We let people know about auditions in lots of ways, from ads in local papers to fliers distributed at festivals," said a rep.
"As part of this normal process, we may inform some acts about the auditions. All acts are auditioned on their own merits and the judges then decide who goes through to the live shows."
Loveable Rogues told Digital Spy last month that they applied for the reality series because they thought "times are changing" for musicians.
"I don't think there are the clubs and gigs out there now where you can get spotted. If there were, we would have done them. We sat down for ages and thought seriously about how long we could do it. Britain's Got Talent seemed like the plausible thing," said singer Eddie Brett.
"If you can't beat them, join them. There's nothing worse than watching people blossom on these programmes, thinking inside to yourself, 'I would wash these people away'."
Simon Cowell hinted heavily that he wanted to sign Loveable Rogues to his Syco label after their semi-final performance earlier this week.
The final Britain's Got Talent semi-final airs tonight (May 10) at 7.30pm on ITV1.
