Ashlee Simpson has slammed Nick Carter’s claims that they slept together while Nick was still with Paris Hilton.

Nick claimed recently that he slept with Ashlee in retaliation when he heard rumours that Paris, who he’d been seeing for eight months, was having an affair.

Nick added that Paris and Ashlee talked about the fling afterwards but Ashlee is denying it all.

When asked if it was true by MSNBC, Ashlee replied: “No! That is so random. When I heard that, I was dying laughing.”

Ashlee is currently appearing in Chicago in London’s West End.
