Mother Monster dropped it pretty quickly, even asking her fans not to say hateful things to the celebrity blogger on her behalf, but Perez still seems pretty heated about the whole thing.
In a new interview with Howard Stern, Gaga finally explained why things turned sour between Perez and the woman he used to call his "wifey."
"The whole thing is really rooted in Madonna," she explained, saying it's a whole thing about whether or not Gaga is the new Madonna or if she's trying to steal her throne.
She also says that they had a falling out when she took two days out of her schedule to do an interview for him and he crossed the line during the interview, being negative about "Born This Way."
"We had had a lot to drink...and he was supposed to be my friend, so I started crying and my friend had to come in and turn the cameras off, they wouldn't turn the cameras off."
She says that he later apologized, but tried to justify his behavior by saying that he's Perez Hilton, and she didn't appreciate him putting his persona ahead of their friendship.
"He's just mad that I don't want to hang out with him anymore," she concluded.
As for him trying to move into her apartment building, she admits that she went "completely crazy" on Twitter when she found out, saying that her sister was sleeping there and she was scared, adding "why do you need to live in my apartment? There's only one reason...to try to hurt me or harm me or blow yourself up."
Yikes! Sounds like there is no reconciliation in the near (or distant) future for these two!
Whose side are you on?
