Apparently using blasphemy as entertainment isn't so cheap after all.
Katy Perry was so surprised by her Grammy nomination for Album of the Year for "Teenage Dream" that she issued a religious expletive when the host of "The Grammy Nominations Concert Live!!" questioned her during the show Wednesday night.
"Are you feeling some Grammy love tonight?" LL Cool J asked Perry, who was seated in the audience wearing a revealing metallic gold dress.
"Hell yes!" she blurted out, before adding, "Excuse me, sorry CBS."
She then held her hands up in a prayer motion and thanked her peers for the nomination.
During the concert, the 25-year-old pop star didn't shy away from impious behavior, engaging in some graphic choreography while performing "California Gurls." While singing the line "so hot/will melt your Popsicle," she gesticulated wildly towards her groin area.
Pulling an about-face after the ceremony, Perry ended her post-Grammy tweet fest with the simple hashtag "#GOD."
Perry's behavior comes as a surprise after she tweeted over the summer that "using blasphemy as entertainment is as cheap as a comedian telling a fart joke."
The post came after Lady Gaga's sexy quasi-religious video for "Alejandro" -- in which she wore a latex nun's habit and was ravaged by a group of scantily clad men -- was released, though Perry denied the two events were related.
Perry, who was raised by Christian pastors and first started singing in church, said she took issue with blasphemous behavior regardless of the perpetrator.
"You know, when Madonna was on a cross, and sometimes my boyfriend will say things that are little bit 'eh' for me from where I come from," she told a French radio station.
Incidentally, Gaga is also nominated for Album of the Year for “Fame Monster,” as are Arcade Fire for "The Suburbs," Eminem for "Recovery” and Lady Antebellum for "Need You Know."
