"People don't understand that I have a great relationship with my parents—like, how that can exist," Perry tells Marie Claire. "There isn't any judgment.

Hudson has attended Perry's megaconcerts before, though he was disturbed by what he saw.
"I was at a concert of Katy's where there were 20,000 people," he says of one performance. "I'm watching this generation, and they were dancing and jumping around. It was almost like church! I stood there and watched how much they were admiring Katy. I thought, 'They're loving and worshipping the wrong thing.' I couldn't help but weep and weep and weep."
Hudson and his wife, Mary, became pastors in the 1980s and traveling evangelists in the '90s. Keith labels himself as an end-times messenger, while Mary is an author and prophet, according to their website.
