Did Katy Perry Dis Lady Gaga’s ‘Alejandro’ Video?

'Using blasphemy as entertainment is as cheap as a comedian telling a fart joke,' singer tweeted.

She liked kissing a girl, but one thing Katy Perry doesn’t take kindly to? Blasphemy.

Katy Perry posted a message on her Twitter page Tuesday that appears to be a direct stab at Lady Gaga’s just-debuted “Alejandro” video and its Madonna-like use of religious imagery .

“Using blasphemy as entertainment is as cheap as a comedian telling a fart joke,” Perry tweeted.

Gaga’s music video — which seems to reference a number of Madonna videos, including “Vogue” and “Like a Prayer” — shows the singer dressed in a red-latex nun’s habit and sucking on rosary beads, and a crucifix appears during a same-sex orgy. There are also clips of flames in the background during one of the dance scenes, reminiscent of when Madonna sang among a field of flaming crosses in her “Like a Prayer” video, which sparked controversy when it was first released.

While Perry has had her own controversial moments — including breakout single “I Kissed a Girl” and a sneak peek of her “California Gurls” video that features a cupcake bra that sprays frosting — she got her start in the Christian-music world and both her parents are pastors.

“I was raised in a very pseudo-strict religious household where the only thing on the menu was [gospel standards like] ‘Oh Happy Day,’ ‘His Eye Is on the Sparrow’ and ‘Amazing Grace’ … all eight verses of it,” Perry told MTV News back in 2008. “So the New Kids on the Block are new to me now; they’re not a comeback. I’m like, ‘Oh, this is a cool song!’ I missed out on a couple other things, but I’m catching up.”
