Lady Gaga and Perez Hilton in Twitter's Feud

Lady Gaga, Perez Hilton

Lady Gaga and Perez Hilton are in the middle of a heated feud, as the former friends have been airing out grievances on Twitter. The root of their disagreements are murky, but Hilton has been gleefully tweeting about the disappointing chart performance of Gaga's new single, "Applause" – particularly in comparison with Katy Perry's new track, "Roar." Gaga responded with a tweet saying Hilton sent her a picture of a wheelchair with the word "karma" written on it the day of her accident that led to surgery and canceled tour dates. The exchanges continued, and yesterday, Gaga posted a since-deleted tweet accusing Hilton of stalking her and claiming he was trying to move into her apartment building in New York.

Hilton responded with a statement to The Hollywood Reporter yesterday, noting he's been receiving death threats from Gaga fans. "My heart hurts that my former very good friend Lady GaGa, 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," he wrote. Though he declined to go into detail on the cause of their rift, he maintained his position as "a critic and not a stalker," and said he isn't a physical threat to the singer. "As the suggestion that I pose a danger to GaGa is preposterous, if fans want to send a message of support to her, they should buy her music," Hilton wrote.

Gaga said fans tipped her off to Hilton's real estate hunting, while a source told The Hollywood Reporter that the blogger was scheduled to visit an apartment in Gaga's building without knowing she also lived there.

The blogger hasn't dropped out of the fight yet: he responded early this morning with tweets that contained veiled references to drug use. "[They] don't just ruin lives. They [ruin] friendships and careers too," Hilton tweeted. "I know some people are sick, and addiction will make you act up, but people need to take accountability for their actions!!!!"
He continued, "I know it's hard to see our idols/friends/people we looked up to as less than awesome. But sometimes those people are so hurtful!"

Lady Gaga's next album, ARTPOP, will be out November 11th.
