`Heartbroken` Katy Perry investing time in herself

London: Katy Perry is no more paying heed to men after his breakup from John Mayer last week.

An insider told Heat magazine that it had been really tough time for Perry, the Sun reported. The source further added that Mayer had just emotionally bailed on her and she couldn’t believe that she was back to square one. The 28-year-old actress had had enough of men and she now plans to throw herself into work projects and hang out with her friends, including her new boyfriend Kristen Stewart. The source continued that Perry is concentrating on healing, working on new music, and spending time with her girlfriends. ANI
