Jessica Simpson's plans to go country have been given a boost - Willie Nelson has agreed to pen tracks for her next album. The pop star/actress' manager-father Joe Simpson revealed his daughter's plans to record a country album in a recent interview - and the With You singer insists she's completely serious. The pretty Texan says, "My next album is probably going to be with Willie Nelson. I've been wanting to do a country record because it's in my roots." Simpson admits she came up with the idea of working with country legend Nelson when they played family in the 2005 comedy, Dukes of Hazzard. She explains, "I aspire to be like Patsy Cline. Willie actually turned me on to her because he used to be one of her background singers."
