An anonymous blog post was spread around internet sites and Twitter this morning, claiming to have insider knowledge on 12-year-old Parke's connections to the company.
However, reps for Syco/Sony Music have issued a statement sternly denying any such links.
"There has been speculation on the internet that Britain's Got Talent finalist Ronan Parke was known to and worked with Syco/Sony Music before entering the show. There is no truth in this story whatsoever," said the spokesperson.
"Ronan first came to Syco/Sony's attention when he entered this year's competition. Syco/Sony Music will not hesitate to take whatever legal action is appropriate to prevent further publication of these unfounded allegations."
Parke was described as a star by the Britain's Got Talent judges after his rendition of 'Feeling Good' at the audition stages. He also won the public vote in the first live semi-final on Monday following his cover of 'Make You Feel My Love'.
He will be one of ten acts taking part in Saturday's live final on ITV1.
