Carter made the claims earlier this week as he described how he got his own back on Hilton for cheating on him.
He said of the situation: ?I just decided to fight back a little bit and started doing my own thing again. The result is I hooked up with Ashlee Simpson. When Paris came back from Australia, they talked to each other and she found out about it.?
However Simpson has denied Carter?s claims and has said: “No! That is so random. When I heard that, I was dying laughing.”
