Aspiring rapper Kevin Federline insists his marriage to Britney Spears will never end in divorce like Nick Lachey and Jessica Simpson's relationship. Federline believes the former NEWLYWEDS: NICK + JESSICA stars didn't work hard enough to keep their relationship together. He explains, "My situation is different. I ain't gettin' no divorce. F**k that! "I don't believe in that s**t. Once you get married, you're in it for the fight." The former back-up dancer believes Lachey is entitled to multi-million dollar alimony payments from his estranged wife - because the couple became even more famous while they were married. He explains, "They did their whole thing together. They really blew up together on that (reality) show. They deserve whatever they get."
