Megan Fox & Brian Austin Green Do a Casual Lunch (PHOTOS)

Shia & Megan Hook-Up?
The star says the two dated.
You’d think Megan Fox and Brian Austin Green were undercover lovers!

The couple went incognito for a lunch at Pinches Tacos in West Hollywood on Friday, with Megan in sweats and her standard baseball hat, and Brian in track pants and a tee-shirt.

Fox and Green prefer to keep a relatively low profile around Hollywood, and we dig it!

Is it just us or does Brian looked like he has slimmed down a bit?
