Celebrity blogger Perez Hilton has taken his cold war with Lady Gaga a step further and posted nude pictures of the singer on Twitter. These have also been linked to her interview with the Guardian, where she admits a drop in popularity.

In the newspaper story Lady Gaga: People Think I'm Finished, the 27-year-old Telephone singer says: "I certainly feel that at this time it's almost as if people are surprised they haven't already destroyed me."

"It's literally not even been two weeks since my first single came out and it's all, 'She's over', or because I'm not No 1 yet, 'She's finished'. People focus less on the music and focus more on how the music's doing; how it's faring from a numbers perspective, from a financial perspective. If you think I give a damn about money then you don't know me as an artist at all," she added, "I think that once you've had a few No 1s in your career that you've kind of proven yourself and I don't feel the need to prove anything anymore."

Although the 35-year-old blogger did not comment on the article, he posted a topless photo of the singer on Twitter - the image was taken for V magazine - and added a link to the interview.

He later added more images, one of which shows Lady Gaga grabbing her crotch. He then tweeted: "@LadyGaGa really loves getting fully naked! And it looks like she doesn't have any hair on her vagina."

Gaga and Hilton, who were once close friends, locked horns after Hilton allegedly sent the Poker Face singer a photo of her in a wheelchair following her hip accident.

"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 tweeted.

The feud heated up after Lady Gaga lashed out at Hilton last month, claiming he was "stalking" her.
