Lady Gaga vs. Perez Hilton: Twitter feud gets monstrous

Lady Gaga's feud with sassy celebrity blogger Perez Hilton is heating up.

The one-time BFFs are airing their dirty laundry on Twitter, and the latest accusation has Hilton (real name Mario Lavandeira Jr.) repeatedly issuing a statement about the whole thing on his blog.

This isn't the first time Hilton has gotten into it with a celebrity. His list of feuds includes spats with will.i.am., Khloe Kardashian and Miss USA runner-up Carrie Prejean. 

But let's rewind on the current kerfuffle, shall we?

The exact origins of the Hilton-Gaga feud are unclear, but Hilton has repeatedly published tweets and blog posts with criticisms about Gaga's latest single, "Applause," calling it "meh" and pointing out its lackluster performance on the charts, especially when compared with Katy Perry's "Roar." Perry recently ousted Lady Gaga as the most followed female celebrity on Twitter too.

Gaga's fans, also known as Little Monsters, did not take the detracting lying down, unleashing a flurry of homophobic abuse at the openly gay blogger and his new son.

The "Born This Way" singer also posted a scathing tweet regarding a pic she'd reportedly received from Hilton following a hip injury at the beginning of the year that landed the singer in a wheelchair.

"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," she wrote on Aug. 16.

Again, the Little Monsters came out in droves and continued to threaten the gossip writer.

Hilton recently announced that he was relocating his family from Los Angeles to New York. Apparently he went house hunting in the Big Apple this weekend, when Gaga said fans tipped her off about him viewing an apartment in her building. That's when she lost it and lashed out on Twitter on Sunday.

"@perezhilton STAY AWAY FROM ME + MY FAMILY YOU ARE SICK TRYING TO RENT AN APARTMENT IN MY BUILDING TO STALK ME. LEAVE ME ALONE!!!" she wrote in tweets that have since been deleted.

"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"
