Paris Hilton and Nick CarterNick Carter has revealed he cheated on Paris Hilton - with Ashlee Simpson - because he thought Paris was cheating on him.

The former Backstreet Boy dated the sociality for eight months in 2004 and has now told the New York Post’s Page Six: “I’d fallen head over heels with this chick. Then, all of a sudden, three months go by and I got people telling me, ‘Nick, you know what Paris is doing to you,’ and I got a little upset.”

“So then 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.”

“So I brought it up to her and said, ‘You know what I did, and now it’s your turn. Why don’t you tell me what you did?’ And she goes, ‘I never did anything! I never cheated on you.’”

“I had kind of started to really like Ashlee and I was thinking about the dating stage, then, before you know it f***ing b*tch-face comes back.”

“I got so burnt over that whole Paris sh*t with all this swinging and switching. Whatever happened to morals and values?”
