Even though they have discussed it, she thought it was too soon. John was gutted,” an insider revealed.“Katy loves John, but doesn’t feel she has had enough healing time since her divorce. She told him she just needed a bit more time to feel whole in herself again.”Perry wed comedian Russell Brand back in 2010, but filed for divorce just 14 months later.
