OOPS, she did it again. Britney Spears has once again changed the date of her wedding to Kevin Federline. Spears had been planning a Los Angeles ceremony on Nov. 20, but ditched the date after word leaked out. Now, it's supposedly been bumped to Nov. 14 in Santa Barbara, according to one person contacted by Spears' camp about working on the nuptials. A rep for Spears told us: "I don't know — I am not involved in the planning and have not received my invite yet."
