Robert Pattinson can't get over Kristen Stewart.

The A-list couple are said to have been secretly meeting up at their mutual friend Shannon Woodward's flat, despite calling time on their relationship earlier this year. "Rob is still in love with Kristen and can't keep away from her. They've been meeting secretly at production studios and at Shannon's flat. The three of them have been close friends for years and all look out for each other," a source said.

Robert, 27, is reportedly finding it impossible to cut ties with Kristen and doesn't want to move on from their four-year romance. "He's tried flirting with other girls, partying and putting distance between them but there's no other woman for him. His sister Lizzie has told him to follow his deepest feelings and to not by swayed by pressure from Hollywood, because his management and publicists want him to move on and leave his 'troubled' relationship with Kristen behind," the insider added.

This comes after the Twilight stars were spotted checking into the plush Viceroy hotel in Palm Springs, California, with their pooches Bear and Bernie last month.
