Did Katy Perry's bikini body break up Robert Pattinson and Kristen Stewart?

katy-perry-bikini-body-gi.jpg Robert Pattinson and Kristen Stewart have reportedly called it quits again and Katy Perry's bodacious bikini body may be partly to blame. Sources tell E! the "Wide Awake" singer "played a role, as one of many reasons" for the latest Robsten split.

And it's no surprise, considering Katy and RPattz have been spotted partying together -- and maybe getting a little too close for K-Stew's comfort -- as far back as a year ago.

Before Kristen's affair with "Snow White and the Huntsman" director Rupert Sanders became public, Perry was seen flirting with Rob at a party while Kristen was in the ladies' room. Later the pair hung out together with Justin Bieber and Selena Gomez on a Hollywood party bus.

Most recently, newly single Katy and not-so-single Rob spent time together before and after the punk rock Met Gala in New York.

Judging by Katy's bikini body, which she readily flaunted on an inner-tubing trip in the Bahamas over the weekend, it's easy to see how she might be a distraction.
