Britain's Got Talent favourite Ronan Parke has dismissed claims that Simon Cowell has been grooming him for stardom for two years as "really silly".
Cowell called in the police after an anonymous internet blogger alleged Ronan already had a management deal and had been moulded to appeal to the audience.
The blogger said the 12-year-old, who will appear in Saturday's final, has been known to Cowell's firm, Syco, for two years.
But the youngster told ITV News: "I have not been coached by anyone to do with Simon. I have never met Simon in my life. I'd love to, but I never have. I have been coached by a singing teacher in Norwich that we pay for. No one's paid for our clothes or anything. It's really silly."
Twitter was buzzing on Thursday with thousands of people posting links to the blog, which also alleged Ronan's hairstyle, clothing and mannerisms were all choreographed.
But the claims resulted in Cowell's lawyers going to a west London police station to report an offence. It is not yet known if officers will take action.
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."
The schoolboy won the viewers' vote on Monday, putting him straight through to the Saturday show.
Syco and Sony Music said in a statement: "There is no truth in this story whatsoever. 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."
