Katy Perry's father, evangelical minister Keith Hudson, recently opened up about his daughter and why he chose to cheer the "Fireworks" singer on during her colorful Super Bowl XLIX halftime performance on Sunday.

"I don't have a problem," he told Daily Mail Online just ahead of Perry's show."She's gonna do some good ones-she's excited [about her Super Bowl performance]."

He added, 'I'm always proud. I'm a proud father.'

The "Roar" singer, who famously started out in the Christian music industry, has often discussed her relationship with her parents, who are both pastors, insisting that they have a great relationship despite having vastly different worldviews.

"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. They don't necessarily agree with everything I do, but I don't necessarily agree with everything they do. They're at peace with-they pray for me is what they do."  

However, the singer noted that she doesn't allow her parents to attend certain performances, such as U.S. President Obama's inauguration, due to their differing political views.

"My parents are Republicans, and I'm not," she also told Marie Claire. "They didn't vote for Obama, but when I was asked to sing at the inauguration, they were like, 'We can come.' And I was like, 'No, you can't."

Perry's parents have previously expressed sorrow over their daughter's decision to abandon her faith and promote a worldview that goes against Biblical instruction.

"They ask how can I preach if I produce a girl who sang about kissing another girl? I was at a concert of Katy's where there were 20,000. I'm watching this generation and they were going at it. It almost looked like church. I stood there and wept and kept on weeping and weeping," Hudson said in a sermon last year. "They're loving and worshipping the wrong thing."

"Satan's assault on our youth is relentless, and they can't fight against it alone," Mary Hudson, Perry's mother, wrote in Charisma magazine. "Parents have to walk in their God-given authority-children can't be left to raise themselves."

But despite claiming she is no longer a Christian, Perry continues to draw attention to her belief in prayer and self-acceptance. Her song, "By the Grace of God," discusses  forward after struggling with severe depression and separating from actor Russell Brand in 2011.

She has also discussed how the Bible verse Psalm 113:9 continues to comfort her during hard times.

"When the Lord took me to that verse, He showed me what was missing," she told Elle magazine. "I needed to get happy before there was anything to be happy about. My attitude had to change. I had to drop the dismal, doubting-Thomas stance to let Him inhabit my praises."
