JESSICA SIMPSON INCOGNITO UNTIL COURIC DEBUT

Jessica Simpson isn't ready to fully show off her new and possibly slimmer body ... going out in only non-revealing clothing and clutching a big bag close to her body. TMZ posted pics of Jess earlier this week ... wearing multiple layers of clothing and holding a giant brown bag. Just this morning at LAX, Jess jetted out of town sporting a similar look, this time with a giant black bag.
