Simon Cowell has called in police over claims that Britain's Got Talent is fixed.
The TV judge made the complaint to officers after an anonymous internet blogger alleged that favourite Ronan Parke had been groomed for stardom.
Ronan, 12, is in Saturday's final and the blogger claimed he had been known to Simon's firm, Syco, for two years.
Tthe blogger also alleged the youngster already has a management deal.
Claims that his hairstyle, clothing and mannerisms were all choreographed were also made.
The allegations resulted in Simon's lawyers going to a west London police station to report the offence.
A Scotland Yard spokesman said: "An allegation of malicious communications was made to Kensington and Chelsea police on Thursday June 2.
"The allegation is being considered."
Syco and Sony Music said they would take legal action to "prevent further publication of these unfounded allegations".
Ronan's mother Maggie also dismissed claims that he was auditioned by talent scouts who spotted him performing at a birthday party for a family friend.
"It's laughable, to be perfectly honest with you, and it couldn't be further from the truth," she told BBC Radio Norfolk.
