Her parents are both Pentecostal pastors and she recently admitted that she wasn't even allowed to watch The Smurfs when she was growing up because of her strict restrictions.
Obviously, when Katy released her controversial song "I Kissed a Girl" back in 2008, her parents weren't too thrilled about the whole thing.
There have even been reports that Katy's dad called her a "devil child" in some of his sermons.
Now, Katy is setting the record straight about her relationship with her parents and while she admits it hasn't exactly been smooth sailing, she says it isn't necessarily terrible, either.
"I have a good relationship with them," she told Elle UK. "It could be better, but it's the same dynamic as most people."
"We love our parents, but we're annoyed by them," she continued. "I respect what they have done for me. I was brought up and surrounded by morality and integrity and that can only be a good thing."
So, it sounds like Katy was just like every other kid who had some growing pains with their parents...the only difference is that hers have been made public because of her celebrity status.
