Perry was spotted with Pattinson on a number of occasions post his breakup, fuelling rumours of romance between them.
"I sent her (Stewart) a text message saying, 'I know you've seen all this stuff but you know I would never disrespect you. I'm not that person. I'm just trying to be a friend to him but it is unfortunate that I do have a set of t*ts'," Britain's ELLE magazine quoted Perry as saying.
Meanwhile, Perry is back with singer John Mayer after a brief split.
