Reese Witherspoon left an office building in LA yesterday. She covered up in a black sweater and carried a bright yellow handbag, which she also took along on a Wednesday outing. Reese's baby bump was barely visible in her gray dress. News of Reese's pregnancy came out last week, just ahead of her 36th birthday and her one-year wedding anniversary with Jim Toth. The triple excitement comes during a busy work period for Reese, who is reportedly producing a children's movie adapted from the book Pennyroyal's Princess Boot Camp.
