The not-so-mysterious blonde: It has been claimed Robert Pattinson's close friendship with British playwright Polly Stenham, pictured, was a 'potential cause' for his split from Kristen Stewart

Their split became official when Robert Pattinson moved his belongings out of the home he shared with long-term love Kristen Stewart last week.
And while it has already been claimed the actor'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 cosy Instagram picture of the pair has emerged, showing the talented 26-year-old with her arm draped around Robert 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 and Polly enjoyed a night of partying together shortly before his shock split from Kristen.
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 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's close friendship with singer Katy Perry was one of the contributing factors to the split.

Beginning of the end: Robert was said to be unable to trust Kristen following her affair with married Snow White And The Huntsman director Rupert Sanders, pictured, last summer

After weathering the storm of her sex scandal with Rupert Sanders last year, Kristen and Robert 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.
