A woman accused of stalking Catherine Zeta-Jones suggested in court that she had a love affair with the film star's husband, Michael Douglas.
Dawnette Knight, 33, told a judge in Los Angeles yesterday that Douglas paid her off after the affair, the New York Post reported.
A lawyer for Swansea-born Oscar winner Zeta Jones, Jay Lavely, dismissed the claim, saying: "It doesn't deserve comment."
Knight, who was recently deemed fit to stand trial despite taking a drug overdose in custody in July, has previously admitted being infatuated with Douglas.
But yesterday, in the witness box, Knight said Douglas gave her money and she strongly suggested the actor and she were having a romance.
"I said I'm not here to ruin anybody's marriage and he's married," Knight said during the ongoing preliminary hearing.
Knight is charged with stalking and 24 counts of making criminal threats against Swansea-born Zeta-Jones.
She is accused of sending letters threatening to kill the star and "feed her to the dogs".
Unemployed Knight, who is in custody, was arrested on June 3 at her home in Beverly Hills. If convicted, she faces up to 19 years in prison.
A day before Knight overdosed on barbiturates Chicago star Zeta-Jones appeared before the court to tell of Knight's alleged reign of terror.
She said she was on the verge of a nervous breakdown as a result of the "satanic" threats.
