Jessica Simpson Defends Her Workout

Jessica Simpson has hired Gwyneth Paltrow's ubertrainer Tracy Anderson to get her in shape for her upcoming wedding, but she claims her workout is nothing new.

"Yes, I am working out, but why is that worth any sorta press? I always take care of myself. Eric and I could get married right now in sweats!" she tweeted on Thursday.

Tracy told Us Weekly that she is having Jessica work out four times a week for 75 minutes at a time. Contrary to what Jessica tweeted, Tracy said that the bride-to-be "is in the mind-set that this is a big, forever lifestyle shift."

Last year Jessica told Lucky that she finally made peace with her curves and stopped fighting to be skinny.
