Is Robert Pattinson's New Girlfriend a Kristen Stewart Lookalike?

Robert Pattinson looks like he has moved on from Kristen Stewart and onto another girl...who also looks like Kristen Stewart.
The 'mystery girl' in RPatz's car is said to be Riley Keough, who is the daughter of Lisa Marie Presley, and the granddaughter of Elvis Presley. 
Riley has acted alongside Kristen Stewart in the movie 'The Runaways', playing the older sister of Dakota Fanning's character.
Some sources have said Riley, who was previously engaged to actor Alex Pettyfer, had always been close to Robert and Kristen while they were a couple... but are things changing now?
Have a look at the photos below - do you see the similarities between Riley and Kristen?
