Polly Stenham: British playwright potential cause of Robert Pattinson and Kristen Stewart split?

Robert Pattinson and Kristen Stewart split became official when he moved his belongings out of the home he shared with the actress last week.

And while it has already been claimed Robert Pattinson’s friendship with singer Katy Perry was one of the reasons behind the doomed romance, it would seem there could be another leading lady who has also come between the couple.

RadarOnline reports the 27-year-old hunk’s close friendship with British playwright Polly Stenham was a “potential cause” for the Twilight co-stars’ sudden split.

And now a cozy Instagram picture of the pair has emerged, showing 26-year-old Polly Stenham with her arm draped around Robert Pattinson and another pal as they enjoyed a night out in New York City.

It is thought the arty black and white snap was taken in early May when Robert Pattinson and Polly Stenham enjoyed a night of partying together shortly before his shock split from Kristen Stewart.

Posted on Instagram by the star’s musician friend Matthew Daniel Siskin, known as Gambles, the undated picture was soon deleted from the social networking site.

Alongside the snap, it said: “Missing the New York crew.”

And it has now been speculated that Polly Stenham was the mystery blonde the actor was spotted enjoying an intimate dinner with at Gemma in the Bowery Hotel on May 3.

A source told HollywoodLife.com at the time: “They seemed like old-time friends.”

However, it has also been claimed that Robert Pattinson’s close friendship with singer Katy Perry was one of the contributing factors to the split.

After weathering the storm of her s** scandal with Rupert Sanders last year, Kristen Stewart and Robert Pattinson reportedly broke up for good earlier this month when he reportedly found text messages from her to the Snow White and The Huntsman director and became upset that they were still in contact.

A source told Life & Style magazine: “Katy never really supported Rob’s decision to get back with Kristen. She always said they wouldn’t last.

“Katy told Rob she didn’t think their relationship could withstand the cheating scandal. And he deserved better than someone who would destroy a family [like Rupert’s].”

A large moving truck picked up the last of Robert Pattinson’s belongings from the former couple’s home in Los Feliz, California, on Thursday.

Robert Pattinson initially struggled to cope with Kristen Stewart’s “momentary indiscretion” with married director Rupert Sanders, with friends revealing their relationship was strained for months after the fling.

A source previously said: “After everything that happened and the hurt she caused, he’s furious she’d be back in touch with him, even if she is saying it’s completely innocent. It does look like this it’s over for good. He simply can’t trust her.”
