We know their rivalry is alive and well via Rolling Stone and Twitter...
Allow us to elaborate on our theory!
Now back to the present…

Kristen Stewart is reportedly calling up and calling OUT Riley Keough for breaking girl code! Friends don't date friends' exes! And Riley broke that rule when she started shacking up with Robert Pattinson!
Sources say KStew picked up the phone and finally CONFRONTED Riley about her and ex-bf Rob's relationship, telling her former co-star she thought their hookups were "really uncool."
Riley might be sorry that Kristen's feelings are hurt, but that's not going to stop her from going steady with Rob! She allegedly can't choose between her old friend and her new man!
The girls ended their phone convo without much closure. Imagine what it's going to be like the next time all 3 of them are in a room together???
What do YOU think??? Is Riley in violation of girl code? Or should Kristen learn to live and let love?
After all, cheaters can't be choosers, Kristen! R-Patz has a pass to pretty much do whatever he wants now!
