  • Hilton realized he didn't need to be mean or cruel on his blog  

Perez Hilton recounted his friendship and falling-out with Lady Gaga. He also admitted that he regretted his decision to have this mean persona but was too afraid to change.

Mario Armando Lavandeira, Jr. a.k.a. Perez Hilton is the person behind the most notorious gossip pages that mock celebrities. In his new memoir "TMI: My Life in Scandal," he shared his regrets about the way he wrote his blog posts and attacked celebrities. He also shared nitty-gritty details about his friendship with Lady Gaga and why he felt that she used him.

Hilton and Gaga met in 2008 and during their first encounter, he felt like he had known Gaga for a long time. There was an instant connection, they quickly became friends and even spoke for hours on the phone, according to him. He even called her "wifey." But the "Poker Face" singer allegedly changed when she became famous.

"As she became Lady Gaga to the world, she began drinking in a different, more serious way, while also popping all kinds of pills," Hilton wrote as quoted by Page Six.

Despite that, Hilton remained a loyal friend to Gaga. When they thought Christina Aguilera copied Gaga on her "Bionic" album, he started trashing Aguilera in his column. 

"I started giving Christina all kinds of terrible nicknames," Hilton added.

"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."

Their friendship imploded in 2011 shortly after the release of her "Born This Way" album. He flew to Australia for an interview because Gaga was promoting her album there. Instead of pushing the interview the following day, they both sat down that night even if they were both jet-lagged and Gaga was drunk.

When Hilton asked Gaga about her controversial single "Judas," she allegedly snapped at him and confronted him about why he made her look bad. He quickly changed the subject and asked her about her boyfriend. But it didn't help because Gaga ended the interview and stormed off.

"If she hadn’t been so drunk and if she had just thought it through, she would have seen that that was the last thing I wanted,” he added.

Two years later, Gaga accused him of being a creepy stalker when her fan saw him looking at an apartment in her building and tweeted about it. Following their falling-out, Hilton said she felt sad for Gaga.

Hilton also made mean comments about Ariana Grande, Roseanne Barr and Johnny Depp. Earlier this year, he apologized to Depp for believing Amber Heard.

In his memoir, Hilton was very sorry for being mean and said he was too afraid to change because he might lose some readers. But now that he is already a father of three, he is more determined to make his column kinder and gentler.

"One of the many things I regret is that I hurt so many people by giving them nasty nicknames, and above all that I was unkind to the children of celebrities," he wrote.

"I now see that I never needed to be so mean or cruel. I would’ve been fine anyway, just by being who I was."
