Simpson annoyed by wedding workout press

Jessica Simpson has confessed that she is confused by the media's obsession with her new workout routine.

The singer - who previously revealed that she is working with celebrity trainer Tracy Anderson to shed pounds before her wedding to Eric Johnson - blasted the press attention via her Twitter page on Thursday.

"Eric and I could get married right now in sweats!" she wrote.

"Yes, I am working out, but why is that worth any sorta press? I always take care of myself."

Simpson and Johnson have not yet decided upon a date for the ceremony.
