Harvey Weinstein Goes Undercover for Dinner with 2 Women (UPDATE)

Weinstein's camp tells us the women came to the meeting to deliver info about an anger management program they're urging him to enter. We're told the trio was waiting to meet with Weinstein's rehab sponsor.

Here's Harvey Weinstein -- or maybe a Blues Brother, or a long-lost member of Run DMC -- wining and dining 2 blondes in the desert.

TMZ obtained the photo, taken last Saturday night at a restaurant in Carefree, AZ ... just outside Phoenix. A witness says Weinstein was at the table waiting for the ladies when they arrived, and he'd pre-ordered 2 glasses of white wine for them. He drank what appeared to be water.

The women appeared captivated by Weinstein's conversation -- but we're told both of them arrived with small portfolios, and it seemed more business-like. They all left together, exiting off the patio instead of walking through the restaurant.

The leather jacket, fedora and shades are, arguably, an upgrade over the wigged out getup he was rocking earlier this month at a different Phoenix-area eatery.
