The ongoing Twitter feud between pop singer-songwriter Lady Gaga and gossip blogger Perez Hilton escalated today with Gaga accusing Hilton of attempting to rent an apartment in her building in order to stalk her.

She got wind of Hilton’s activities earlier this morning via Twitter user @PrinceNeptune_:

Gaga claims that staffers at her apartment building confirmed the Twitter user’s claim:

So far, the claims made by Gaga and her source are just allegations. No response yet from Hilton. Twitchy will monitor the story and will update this post with any new developments.

Hilton has responded:

I love New York and that is where me and my growing family want to call home right now. 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. While it is still too painful for me to go into detail about why I chose to no longer make her a part of my life, I will say that I am a critic and not a “stalker”. 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.

Gaga has deleted all of the above tweets.
