Kristen Stewart and her on-again off-again boyfriend Robert Pattinson, who were rumored to have split up in May, were reportedly seen holding hands while out on a walk in LA. An eyewitness told E! Online that the former ‘Twilight’ co-stars were seen strolling around in laid-back duds and looking quite friendly, the New York Daily News reported. The source said that the duo was talking closely and Pattinson seemed protective of Stewart, but apart from that there was no PDA. This incident occurred just a week after it was reported that the ‘Snow White and the Huntsman’ actress and her pal Katy Perry had fallen out over Perry’s recent over-friendly behavior with her beau.
