He can't resist dat ass!
Robert Pattinson and his girlfriend FKA Twigs have been adorably going strong, and they're not afraid to hide it!
After lunching together on Friday in Los Angeles, the casual couple left the eatery, and Mr. Pattinson was feeling frisky!
He kept his hand right on his lady's perky behind the entire time!
With a booty like that, we can't blame him one bit!
