Everyone has an "off" day... apparently even Megan Fox! The sexy Hollywood star was out having lunch in Los Angeles with her husband, Brian Austin Green, in sweats and a baseball cap on Saturday afternoon. But, when Megan spotted the paparazzi, she got camera shy!

Brian helped his wife out by covering her face with his tatted-up arm. Was Mrs. Foxy not feeling the attention because it was a no-makeup day? Or was she hiding a blemish, tears, or something more serious, like evidence of cosmetic surgery?

Yes, we went that far, because there's no reason on earth why a babe as naturally blessed as Megan Fox should ever hide her face, unless she's hiding something major. We all have bad days, Megan, but you can grin and bear it!
