Orlando Bloom took fans aback when he was busted checking out Kim Kardashian’s butt at a gala in New York City this week, but a source exclusively tells Life & Style Katy Perry couldn’t have cared less and they both actually encourage each other to get their flirt on!

Katy Perry reveals that Orlando Bloom's son Flynn, 13, helps her out with her music, saying that he "has a really good ear." The singer shares her daughter Daisy with Bloom, while he shares Flynn with ex Miranda Kerr.

Perry’s birth name is Katheryn Hudson and she released a Christian rock album in 2001 called “Katy Hudson” before she released her breakthrough 2008 album, “One of the Boys,” recorded under the name Katy Perry. "Perry has taken her mother’s maiden name to avoid confusion with Kate Hudson," Rolling Stone reported in a 2010 profile of the singer.
