Talk about a photo op! A bloodied Lady Gaga met up backstage after her concert in Phoenix, Arizona with her idol Alice Cooper. Looks like the 24-year-old singer is all choked up!

While showing off her black undies and banging body, Lady G tweeted this photo with the following:

    "I just died and went to hell."


Gaga will reportedly join Cooper on one of his upcoming shows. Find out when and where ... after the jump.
