Britney Spear's first husband Jason Alexander has claimed that the "Toxic" singer left a threatening message on his telephone.
Alexander married his childhood friend at the little white wedding chapel in Las Vegas in January 2004 but wedlock lasted just 55 hours before the vows were annulled.
Appearing on the Dr Keith Ablow show, Alexander claimed that a voicemail message from Britney said: "don't say anything you'd regret".
Britney, who celebrated her 25th birthday on Saturday, has sold over 80 million records worldwide, has her own perfume range and has even been in the odd movie.
Since child star and global pop phenomenon, Britney Spears, announced that she and aspiring rapper Kevin Federline would be filing for divorce on the grounds of irreconcilable differences the press just can't get enough of her and her high-profile partying with hotel heiress Paris Hilton.
The pair have two children together, Sean Preston and Jayden James, from their two year marriage. Dancer Federline will reportedly received $300,000 (£151,713) from Britney in the divorce as part of the pre-nuptial agreements and half of the proceeds from the sale of their home.
