Lady Gaga reveals cause of Perez Hilton feud

Lady Gaga revealed the genesis of her feud with Perez Hilton Tuesday on Howard Stern's radio show, prompting an immediate reply from the entertainment blogger.

"What happened was . . . I took two days out of my schedule when I was on a world tour to do an interview for him to support a show he was doing," Gaga recalled, "and in the middle of the interview he started asking me really terrible questions and he was being very negative about 'Born This Way' . . . And he was supposed to be my friend and I felt betrayed, so I started crying."

Hilton apologized, she said, "but I sort of felt like it was like, 'But I'm Perez Hilton so I'm allowed to treat you this way.' . . . And I was done after that."

Gaga said she felt betrayed because "I really supported him and I made sure that if people didn't want him to come into award shows or things like that, that I would fight for him to get in. And I'm thinking, 'My God . . . you've been with my family, we've eaten together, how could you ask me these [questions]? He was just framing everything like I was some sort of a failure now. And it really was hurtful."

Hilton responded with tweets saying, "I was the one who pulled away from you after I realized what a real-life vampire you are!" and telling Stern, "Reach out to me if you want me to come in and speak the truth about Lady Gaga!"
