After endless denials, Jessica Simpson and Nick Lachey confirm to Us Weekly that they have split.A month after Us first reported the split, the couple jointly announced an official separation. "After three years of marriage, and careful thought and consideration, we have decided to part ways," they said in a statement. "This is the mutual decision of two people with an enormous amount of respect and admiration for each other. We hope that you respect our privacy during this difficult time."When Us first broke the story on October 6, publicists for both stars issued denials. But the couple rarely was seen together after that. Jessica frequently was without her wedding ring and spent their anniversary in Africa; Nick was often seen partying and there were rumors he hooked up with some college chick. Last night he attended the American Music Awards by himself.The biggest loser in the situation is Jessica's father, Joe Simpson, who basically swore on his life that the couple was still happily married. The truth is, he has a huge stake in keeping them together as Jessica's manager. And his daughter will probably also have to pay Nick a pretty penny in alimony. She's worth a lot more than he is.After dating for a few years, Nick and his virgin bride Jessica tied the knot in Austin, Texas in October 2002. Still relatively unknown at the time, the couple then signed on to do a reality show for MTV about their first year of marriage called Newlyweds. The show catapulted them to mainstream fame -- they both released albums, Jess starred in Dukes of Hazzard last year and also launched product lines (body lotions and clothing). In 2004, Jessica earned $35 million.Interestingly, when Jessica started filming Dukes is when talk of trouble in their marriage began. With her hot new bod, she started hitting the club scene and really enjoyed the attention she was getting from men, including her married Dukescostar Johnny Knoxville. There were rumors of romance between the costars, as well as a fling between Jess and Jackass star Bam Margera. Maybe now that they are finally coming clean, they can move on with their lives. I can't wait to see who they hook up with next!
