Lady Gaga Manages To Surprise Australians With Crudity

And she's coming to San Jose in August. Caveat emptor!:

SHE pretends to eat human hearts, bathes in blood and vomit, simulates sex and does it all in front of tens of thousands of screaming fans.

But there is no age restriction preventing children attending the controversial concerts of American pop sensation Lady Gaga, who performs in Adelaide on April 3.

Her Australian tour has been attacked for pushing vulgar and offensive themes on to her young fans.

The show features bulimia, binge drinking and constant expletives, making chaperoning parents think twice about Gaga's latest act of pop defiance.

During her tour, aptly titled Monster Ball, the Grammy Award-winning singer takes the audience into a gothic Wizard of Oz wonderland, where a video of a model making herself vomit on to Lady Gaga is shown on a film loop.

Linda Fitzsimmons, who took her nine-year-old daughter Jessica to Lady Gaga's Sydney show on Wednesday, has called for a rating system for live music shows similar to movie classification.

"I was shocked and surprised," she said.

"I couldn't believe it. (Jessica) likes her songs and I'm OK with her listening to them. There's no swearing in them . . . " she said.

"But if I tried to take her to an MA 15+ movie, someone would stop me at the counter. Why not with concerts?"
