Perry appeared to be commenting on Gaga's controversial new "Alejandro" video last week when she tweeted, "Using blasphemy as entertainment is as cheap as a comedian telling a fart joke."
The promo features Gaga, dressed in a latex nuns' outfit, suggestively swallowing a string of rosary beads. Scenes also show the outrageous star simulating sex with a group of scantily-clad male dancers, wearing only her underwear.
Perry, who got her start in the Christian music and is the daughter of church ministers, appeared to be taking aim at her on Twitter.com shortly after the video was released online.
But now the "California Gurls" singer, who is engaged to controversial comedian Russell Brand, insists she respects Gaga's point of view, even if she disagrees with her use of religious imagery.
She tells a French radio station (via PerezHilton.com), "Lately, I've just been seeing some things that are kind of ... not something I would do, I guess. Like, you know, when Madonna was on the cross (on her most recent world tour).
"(People say) I'm a very hypocritical person, 'How do you say that and (sing), 'I Kissed a Girl?' Spirituality and sexuality are two separate things. When you decide to put it into the same subject, it gets interesting for some people.
"Everyone knows... I've said 100 times on my Twitter: 'I'm one of the biggest Lady Gaga and Madonna and Russell Brand fans.' Some people have different view points."
Gaga has defended the "Alejandro" video since its release, calling it "a celebration and an admiration of gay love."
