BACKSTREET BOY NICK CARTER has ruled out ever getting back together with his ex Paris Hilton - because she isn't "intelligent" enough. But Carter, who split from the hotel heiress in July 2004 after dating for seven months, insists his experience with Hilton has not put him off dating another high-profile star. He says, "There's no way I'd get back with her (Hilton). I'd go out with another celebrity if she was the right girl. She'd need to be able to have an intelligent conversation, though." When asked if Hilton could engage in such talk, he added, "No."
