Team R. Pattz all the way.

If there's anyone out there who knows the pain and the embarrassment of a public split, it's Katy Perry. That's why the 'Wide Awake' singer has jumped to support heartthrob actor Robert Pattinson, who, along with the rest of the world, learned last week that his girlfriend and 'Twilight' co-star Kristen Stewart had cheated on him.

The scandal has rocked the teen entertainment world to its very core, since, essentially, Bella cheated on Edward. Gasp! Perry, however, is firmly team R. Pattz as opposed to Team K. Stew.

Pattinson, who reportedly moved out of the couple's Los Angeles home after K. Stew issued a public apology for her indiscretion when photos of her in a compromising position with her 'Snow White and the Huntsman' director landed in a tabloid, supported Perry when she split with husband Russell Brand. So now Perry is returning the favor. But don’t be so quick to jump on those 'Perrinson' or 'Robkat' bandwagons, people. They are just friends.

A source told The Daily Star (quotes courtesy of Female First), "Katy has been a rock for Rob. She has reassured him she is very much there for him just as he was for her when she split from Russell. She has urged him to take a break with her [Stewart]."

Perry, who shared an intimate glimpse of the pain from her split with Brand in her flop film 'Katy Perry: Part of Me,' has the type of firsthand experience to help Pattinson navigate the pain, humiliation and anguish that comes along with breaking up in Hollywood. At least R. Pattz doesn't have to deal with his equally famous girlfriend cheating on him and getting caught on his own.
