Katy Perry found Lady Gaga’s ‘Alejandro’ video offensive

The 'I Kissed A Girl' hitmaker is "sensitive" about the Christianity referencing promo - which features Gaga putting rosary beads in her mouth while dressed as a nun – and insists even her fiance Russell Brand cannot get away with blasphemy.

Katy – whose parents are both Christian pastors - said: "I am sensitive to Russell taking the Lord's name in vain and to Lady Gaga putting a rosary in her mouth. I think when you put sex and spirituality in the same bottle and shake it up, bad things happen.

"Yes, I said I kissed a girl. But I didn't say I kissed a girl while f***ing a crucifix."

Just as religion bashing makes her mad, the 25-year-old pop star is also infuriated by celebrities who claim they don't read gossip about themselves on the internet.

She added to Rolling Stone magazine: "Any artist who says they don't Google their name is a big fat liar. It's a little gross when you look at other celebrities' twitter feeds and see them posting about something they read about themselves on a Google Alert, it's like, 'Uh, maybe you should stop Googling yourself every day, the world does not spin around you.' "
