's post- dating life could be over before it has even begun. No sooner had he been linked - admittedly, very loosely - to Elvis Presley's granddaughter, , than he allegedly backed off in deference to K-Stew's feelings.
A source at Hollywood Life said:
Rob’s schedule is very busy and he is in no mood to start another relationship, especially with someone so close to Kristen. He doesn’t want to be ‘that guy.’ He doesn’t want people to think he is stealing a friend in the wake of the relationship with Kristen.
He loved Kristen and always will look at her fondly, but he doesn’t want to be defined by her, and by dating Riley it would only continue the link to Kristen.
Stewart and Keough became friends when they worked together on Joan Jett biopic The Runaways, and it's likely that R-Pattz cut ties with Keough to preserve the girls' friendship as well as his own feelings for Kristen. However, an eyewitness at a recent Joan Jett concert - at which Kristen and Riley were both in attendance - hints that the damage may have already been done:
Kristen watched the show from upstairs and I am pretty sure Riley kept her distance and was watching from downstairs. It was weird when they saw each other, because Kristen didn’t look very happy when she walked over to give her a hug. Can we say awkward and tense?
Robsten hardly need any more friction in their already difficult on-off relationship, although the fact that it is practically impossible to find a photo of Rob and Riley together suggests that his 'relationship' with Keough is not the biggest threat to a Robsten reunion.
