The blogger, 42, who met the singer in 2008, made the sensational allegations in his new memoir, TMI: My Life in Scandal.

Perez claimed they hit it off straight away, went on holidays together, spoke on the phone for hours a day and were so close that he called her “wifey,” Page Six reported.

The columnist alleged that Lady Gaga quickly began drinking heavily and doing drugs.

He wrote: “As she became Lady Gaga to the world, she began drinking in a different, more serious way, while also popping all kinds of pills.”

The 34-year-old singer has spoken openly about her use of drugs in the past.

In 2013, the singer – who recently revealed she’s on anti-pyschotic medication – said she used drugs to cope with the pain of her hip injury, which left her in a wheelchair after she had surgery a year earlier.

She told radio station Z100: “I have been addicted to it and it’s ultimately related to anxiety coping and it’s a form of self-medication and I was smoking up to 15-20 marijuana cigarettes a day with no tobacco.

“I was living on a totally other psychedelic plane, numbing myself completely, and looking back I do see now that some of it had to do with my hip pain… I didn’t know where the pain was coming from so I was just in a lot of pain and very depressed all the time and not really sure why.”

Back in May, The Grammy winner said she has quit smoking and is “flirting” with being sober.

Elsewhere in his memoir, Perez claimed he and Lady Gaga would trash Christina Aguilera after speculating that she had copied Gaga’s “sound and visuals” for one of her albums.

Perez said he regretted giving Christina – who had performed at his birthday party – “all kinds of terrible nicknames.”

He wrote: “Looking back now, it’s one of the things I’m most ashamed of, and I can also see that Gaga was using me as a tool – not only against Christina but against other rivals too.

“She never explicitly asked me to write nasty things about people, but by moaning to me she made me feel like I, her best friend, should do something about it.”

His friendship with Lady Gaga came to an end in 2011, after an interview in Australia following the release of her Born This Way album.

Perez claimed Gaga was “so drunk” during their chat that she “snapped” and “stormed off” when he asked her about the controversial religious imagery in her Judas music video and her boyfriend at the time.

Two years later, the Bad Romance hitmaker reportedly accused him of “stalking” her after he was spotted apartment hunting in New York.

Perez realized the claims were sparked by him “unknowingly” looking at an apartment in Gaga’s building.

Lady Gaga previously shut down any claims of a feud with Christina, calling the speculation “sexist”.

She said in 2013: “I’m a very big fan of Christina Aguilera. From the very beginning of when my career started, there was all this controversy about the two of us and I always felt it was very unfair to her.

“From me to her, I’m so sorry for anything that anyone ever said to her because of my existence, and I hope she never felt any way about it, because when I was 15, I was singing I Turn to You at the top of my lungs trying to hit all her notes.

“She was an inspiration to me to have a wider vocal range, and I just think it’s all total nonsense.”
