This is has been gossiped about for so long, who knows if it's true. According to ETONLINE.COM Nick & Jessica: Is It Over? October 5, 2005 Is it really over for "Newlyweds" couple JESSICA SIMPSON and NICK LACHEY? According to this Friday's issue of Us Weekly the popular twosome, who have been shooing away break up rumors for the past year, are no longer together. But Nick's representative tells ET that the reports are "not true." In a joint statment on behalf of Nick and Jessica his rep says: "Nick and Jessica have not separated. Rumors to the contrary are simply not true." The pair were last seen together publicly on September 11 when they sang a duet at an NFL football game. According to the magazine, rumors of a split started to swirl again when Jessica arrived solo (and without her wedding ring) to her sister ASHLEE's 21st birthday in Las Vegas last weekend and Lachey, who was scheduled to be there, was a no-show. Us Weekly sources also claim it was her ego, her partying and her dad that drove the couple, who will celebrate their 3rd wedding anniversary on October 26, apart. Just days ago, while talking about her new body care collection "Sweet Kisses," available at Wal-Mart, Jessica spoke with ET's CHRISHAUNDA LEE, offering marriage advice. "I think you have to always remember, and he has to remember, that you do need a compromise, even though it's hard," she said. She admitted though, that sometimes strong personalities can get in the way of marital negotiations. "There's people with pride involved," she says. "You have to back down sometime -- just a little bit." For more on the Nick and Jessica split speculations, watch tonight's ET.
