WASHINGTON (CBS DC) — Pop star Katy Perry, who will be featured on the cover of the January 2014 issue of Marie Claire, told the magazine that she refused to allow her parents to watch her sing at President Obama’s inauguration “on principle,” and because they are Republicans.

“My parents are Republicans, and I’m not. 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,’” she told the magazine.

She continued, even expressing a bit of anger at her parents’ offer to see their more liberal-minded daughter sing at the January 2013 inauguration for President Barack Obama in Washington D.C.

“I love you so much, but that—on principle.’ They understood, but I was like, ‘How dare you?’ in a way.”

Perry performed multiple times on the campaign trail for President Obama, and was seen the week of the inauguration in photos posing with First Lady Michelle Obama and sipping wine with singer John Mayer.

The magazine and other sources have labeled her parents – Keith Hudson and Mary Perry Hudson – as “evangelicals” and “ultra-conservative.”

Perry told the magazine that her parents met at a Las Vegas tent revival when her mother was a “pot-smoking debutante” and her dad was “an acid-dropping hippie-turned preacher.” She said that regardless of differences they maintain a great relationship.

“People don’t understand that I have a great relationship with my parents—like, how that can exist,” she told 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.”

“They’re fascinated with the idea that they created someone who has this much attention on her.”
