'He asked me terrible questions.' How Lady Gaga and Perez Hilton's friendship disintegrated.

In the late noughties and early 2010s, Perez Hilton and Lady Gaga were best friends.

The celebrity gossip blogger rose to notoriety in 2004, known for being horrifically harsh in his unpacking of celebrity culture. He has been a fixture in gossip media ever since.

As his success in the media grew, he frequently found himself as a friend to those celebrities he was blogging about. That included Lady Gaga, now 33, who at the time was gaining fame for her popular songs like ‘Just Dance’ and ‘Paparazzi’.

But as Gaga's success continued to blossom, her friendship with Hilton soon disintegrated.

In a recent episode of the podcast Daddy Issues, Hilton, 41, explained their relationship breakdown.

"Fame can be a very toxic thing depending on what kind of a person you are," Hilton shared.

"She’s very famous now but back in 2010-2011, it was what Ariana Grande is going through now. Every song was a hit, she was everywhere, non-stop media attention.

"It’s not easy for a lot of people to deal with that kind of fame and it can consume you," he continued. "She fell out with not just me but everybody."

It's not the first time Hilton or Gaga have spoken about their friendship fallout publicly.

It all started in Australia in 2011, when Gaga was filming a cooking segment and being interviewed by Perez Hilton.

"What happened was we were doing an interview – I took two days out of my schedule when I was on a world tour to do an interview for him," Gaga recalled to Howard Stern during a 2013 interview. "In the middle of the interview he started asking me really terrible questions and he was being very negative about 'Born This Way' and we had had a lot to drink."

"He was supposed to be my friend and I felt betrayed, so I started crying. And then my friend had to come in and pull the camera out, they wouldn't turn the cameras off."

She continued: "He apologised, but I sort of felt like it was like, 'But I'm Perez Hilton so I'm allowed to treat you this way.' I looked at him and said, 'Just because you are who you are, does not mean that our friendship doesn't mean anything when the cameras turn on. So, now I see who you really are.' And I was done after that."

Their feud continued to play out in public, both often posting tweets out to their millions of followers slamming one another.

In 2013, Lady Gaga accused the celebrity gossip of stalking her, writing in a since-deleted tweet: "STAY AWAY FROM ME + MY FAMILY YOU ARE SICK TRYING TO RENT AN APARTMENT IN MY BUILDING TO STALK ME. LEAVE ME ALONE!!!"

Hilton has been in the headlines recently after another one of his famous feuds regained public attention – his conflict with Mischa Barton.

During the first episode of the renewed season of The Hills: New Beginnings, actress Mischa Barton opened up about her feud with the celebrity blogger.

"Perez was a total bully back in the day, he was awful to me and lots of women.

"There was a lot of pressure to be really skinny. It's hard when you're young, you take these things to heart," she said.

Asked if he ever apologised, Mischa responded, "I don't think he really did."

Perez is due to appear in episode two of The Hills: New Beginnings.
