Lady Gaga is furious with blogger Perez Hilton and has accused him of stalking her by renting an apartment in the building she stays.

Lady Gaga accused blogger Perez Hilton of stalking her by renting an apartment in the very building she lives in. She even asked her fans to post a picture of the blogger in her building for her. As the tweet of the Mother Monster hit the social networking site, millions of fans got furious and threatened to kill Hilton's son.

Such threats by her fans are common for anyone who gets in the singer's bad books.

The uproar began when Gaga's fans alerted her that they had spotted the blogger in her apartment building.

"@perezhilton STAY AWAY FROM ME + MY FAMILY YOU ARE SICK TRYING TO RENT AN APARTMENT IN MY BUILDING TO STALK ME. LEAVE ME ALONE!!!" Gaga tweeted Sunday.

"DO I NEED TO BE SHOT IT IN THE HEAD FOR PEOPLE TO UNDERSTAND THAT HIM AND EVERYONE ELSE THAT HARASSES ME HAS GONE TOO FAR? IM A HUMAN BEING," Gaga added.

Gaga and Perez were great friends when she started out in the music business but with time the friendship turned sour. But most recently, Perez has been accused of stalking the "Applause" singer. The blogger, however, denies all accusations of stalking the singer.

"Sunday, my realtor showed us a list of possible apartments to rent. I learned only after the fact that Lady GaGa lives in one of the buildings we looked at, and she was across the country in Los Angeles when I viewed that building. After a day of innocent house-hunting, I am devastated and my heart hurts that my former very good friend, a person I used to call my "wifey" and traveled the world with, is making very public and very untrue allegations about me on Twitter," Hilton wrote in a response statement on his blogging site.

"Any allegation that I am stalking her, based on a day of house hunting with my baby boy and my mother, is utterly false, defamatory and now appears to be putting me and my family in danger," he added.

But the threats are unlikely to change his profession and free will to criticize songs, like Gaga's "Applause."

But his statement had no effect on the little monsters who continued to threaten the blogger.

"@PerezHilton we will kill you bitch #OperationKillThePig," tweeted @ilyessiag.

"I'm going to kidnap ur son  @PerezHilton" wrote another user @YeezusCunt.

"I can't sleep. I am literally sick to my stomach. Not playing any fucking games here. I am afraid for my fucking safety and that of my son," Hilton tweeted Monday, in response to several hate  tweets.
