David Beckham issued a statement tonight to say there was "absolutely no truth" in rumours about him on the Internet.
Web users around the world have been circulating claims about the Manchester United star which first appeared on a web site.
But in a statement tonight, his spokeswoman said that repeating the rumours could result in legal action.
The spokeswoman said: "We are aware that there are malicious rumours circulating in the media about David Beckham.
"There is absolutely no truth whatsoever in these rumours and the web site we believe to be the source of these rumours has been contacted and all defamatory material has been removed.
"No publication of these rumours should be made as it would result in legal liability for defamation.
Beckham, who is currently recovering from a rib injury, and his wife Victoria returned from a Caribbean holiday yesterday with their two sons Brooklyn and Romeo. The couple spent a week enjoying the sunshine in Barbados and flew back to Heathrow Airport.
