Christina Aguilera slams tabloids, Simon Cowell

• 'The Voice' judge 'trash' talks tabloids.
• Aguilera calls Cowell a vulgar term.
• The frank-talk fest happened Thursday at a 'Billboard/Hollywood Reporter' event.

She may be beautiful, but during a Q and A Thursday, Christina Aguilera was sounding more like her old dirrty girl self.

At the Billboard/Hollywood Reporter Film & TV Conference, The Voice judge leveled a litany of family-unfriendly epithets against bloggers, tabloids and her singing competition-show rival, Simon Cowell.

On the tabloid press and bloggers: "I don't read blogs. It's just God-knows-who in (expletive) wherever writing hate (expletive). You can't take it seriously. I'm sure you've all been hated on at some point by (expletive) people."

On Cowell: "I saw the commercials early on of American Idol of Simon being a (vulgar term). I was like, 'Man, that's not what it's about!' I didn't want to treat people like that. I wanted to do The Voice to show that we can be positive. We don't have to knock people down."

And then, as if it wasn't clear, "It's real talk today," she told the crowd, who applauded.

She also talked frankly about distancing herself, musically speaking, from a fellow diva when it came to recording Beautiful. As Xtina recalled, songwriter Linda Perry told her: " 'Don't do all that Mariah (expletive)' — that was her, not me, I love that (expletive)! But she was like, 'Don't be doing all that acrobatic (expletive), just sing!' "
