Lady Gaga Gets Bloody W/ Alice Cooper, "I Just Died & Went To hell" (PHOTOS)

Lady Gaga got a nice surprise backstage at her recent concert in Phoenix, Ariz. - she met her idol, original shock-rocker Alice Cooper and Tweeted a picture from their meeting yesterday - her birthday.

"I just died and went to Hell,"

she Tweeted - along with the picture of herself covered in fake blood and her idol's hand around her neck.



While Gaga is a huge fan of Cooper, the macabre rocker also finds himself a fan of hers.

"She's a cross between Madonna, Mae West and Liberace... She's a spectacle."

"She's great because she gets it, but she can back it up. She can sing, she can write, she can play piano, she's not just a costume queen,"

he says.

"You can be as outrageous as you wanna be, as long as you can back it up with the music. She said, 'if you're gonna do it, go as far out on a limb as you can, like Alice Cooper did.' She's totally outrageous. Lady Gaga's already in the history of rock 'n' roll.

"I see bands and I go, 'What, he went down to Gap and bought a pair of corduroys and a shirt?' What fun is that? Nobody will remember 90% of the rock bands, but they'll remember Gaga,"

he adds.

After meeting her hero, Lady Gaga asked Cooper if she could make a cameo appearance in one of his famous stage shows - which often include morbid scenery including many death devices, such as a gallows or guillotine and lots of fake blood.

Sources say that it could happen as soon as this May, when both artists' tours will be in Brazil at the same time.

And speaking of the history of rock 'n' roll, Cooper, 63, was inducted into the Rock and Roll Hall of Fame earlier this month.
