Katy Perry Takes Swipe at Her Parents

Katy Perry lashed out at her parents last night for playing armchair quarterbacks in her divorce with Russell Brand.

Keith and Mary Hudson, who are ministers, said earlier this week ... the blessing in Katy's divorce is that it created interest in their ministry.

Katy tweeted last night ...  she was " grateful for all the love and support" she's gotten from her fans. But she followed that up by saying that no one speaks for her ... including her family. 

Seems she is pissed ...
