Perez Hilton Stalking Lady Gaga? 'Mother Monster' Calls Out Perez on Twitter, Calls Him 'Sick,' Did He Try to Buy Apartment In Gaga's Building?

Lady Gaga and Perez Hilton's feud has gone to a whole new level. Gaga called out Perez on Twitter Sunday after she alleges that the gossip blogger was looking at apartments in her building in order to stalk her. Gaga and Hilton had a very public fight after "Mother Monster" took to Twitter recently to call Perez out for a text he sent to her after she suffered her hip injury.

It looks like the feud continues to heat up. Hilton has been openly critical of Gaga, including her new single "Applause." Gaga had to call off her "Little Monsters" recently, but it seems the feud isn't close to ending.

"@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 on 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 continued.

Perez just responded early Sunday evening. Or I'm guessing the following tweets are his response to Gaga's accusations. "I have a 19 inch penis! #DontBelieveEverythingSomeoneTweets" Perez tweeted. "No one is objective. #EveryoneHasAnAgenda" Perez continued. The gossip blogger then tweeted a link to Katy Perry's "Roar" music video. Another shot at Gaga perhaps?

It was just days ago that Gaga tweeted that she still has the texts the gossip blogger sent her after her hip surgery. "Still have the text Perez sent me of me in a wheelchair w the words KARMA written across + Madonna pointing a gun at me. Day of my accident," Gaga tweeted.

The drama continues.
