PARIS Hilton has backed Cheryl Cole's bid to crack America. The hotel heiress, who has been in the UK promoting her TV show My British Best Friend, thinks the brunette will go down a storm Stateside. Paris wrote in Heat magazine: "She's stunning and I bet they'll love her in the States." The Girls Aloud star's US bid will be helped along by The X Factor's Simon Cowell, who is said to be determined to launch her career there. Paris said she thinks it's a "wise" move on Simon's part - and revealed she's a big fan of his, saying he's "very funny, charming and cool". "I haven't invited him to the nightclub in my house yet - but I will" said the socialite, who recently split from Good Charlotte rocker Benji Madden. The socialite also vowed to keep the world economy afloat by continuing to go shopping. Paris said: "It's really scary about the economy right now. So the way I'm playing my part in helping is doing a lot of shopping wherever I go. "I think a way for people to get by in this economy and still be fashionable is to go to Topshop, because they have really cute clothes at great prices." " Agencies
