The source told the publication: “[These claims] are absurd and there is no way her attorney, a former federal prosecutor, would ever let anyone ever extort Britney Spears.”
Spears has worked with Wasser before, after hiring her to battle her ex-husband Kevin Federline, 45, for custody over their sons, Sean Preston, 17, and Jayden James, 16.
She was ordered to pay US$20,000 in child support at the time, which Wasser said Spears felt “great” about. Kevin now has full custody of their sons.
Spears and Asghari’s break up was first reported on Wednesday (US time), with the split said to have come after the budding actor confronted her over rumours she had been unfaithful.
A source with “direct knowledge” of the couple’s alleged break-up told TMZ that Asghari has moved out of their mansion, and added: “It’s only a matter of time before Sam files for divorce.”
Spears and Asghari haven’t commented on the report.
