"Katy and John remain friends and care about each other. They just want to see each other happy. They have no animosity towards each other," a source said.
However, her friendship with Mayer is not a problem for her current alleged boyfriend Orlando Bloom and things have reportedly gotten so serious between Perry and the "Lord of the Rings" actor.

Flynn's mother is model Miranda Kerr, who Bloom split from in 2013 after three years of marriage.
