The feud between the pop star and the pop culture blogger has reached new heights as Lady Gaga claims on Twitter that Perez Hilton has been stalking her.

HuffingtonPost reported that a Twitter fan of Gaga's claimed Hilton was in her building in New York. Gaga then took to Twitter and confronted Hilton. She wrote, "STAY AWAY FROM ME + MY FAMILY YOU ARE SICK TRYING TO RENT AN APARTMENT IN MY BUILDING TO STALK ME. LEAVE ME ALONE!!!" She also added, "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."

According to CNN Hilton responded to the claims through a blog post. The post was titled "A Statement On Lady GaGa's Lies." In it, he explained that he was in New York searching for a new home and addressed Gaga's claims. He wrote, "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."

TheCelebrityCafe.com has reported that the two former friends began feuding after Hilton criticized Gaga's latest single, "Applause."
