As celebrity gossip goes, it takes some beating: actor and model Elizabeth Hurley had a year-long affair with Bill Clinton while he was US President.
Throw in the suggestion that they had a liaison in the White House while Hillary Clinton was next door, and that Mr Clinton ended it when he realised he was falling in love, and you have a story that rivals Marilyn Monroe's alleged fling with John F. Kennedy.
But when something sounds too good to be true, it usually is, as Miss Hurley pointed out yesterday when she was forced to deny the "ludicrously silly" report and threatened legal action as it gathered pace online.
The allegations were made by Tom Sizemore, a Hollywood actor who claims to have dated Miss Hurley in the 1990s.
Sizemore was recorded on video boasting to friends he had arranged Miss Hurley's first rendezvous with the President in 1998 after a White House screening of Saving Private Ryan.
