Alex Pettyfer has finally copped to feuding with his Magic Mike co-star Channing Tatum. And in a moment of surprising maturity, Pettyfer admitted he's to blame for earning the wrath of Hollywood's favorite bro.

"It's true," Pettyfer admitted on Bret Easton Ellis' podcast. "Because Channing Tatum does not like me - and for many reasons, many being my own fault."

When director Steven Soderbergh initially approached Pettyfer about starring in the stripper drama, the actor had an extremely bad reputation, both in his personal and professional lives. "[Tatum] was not sold on me being a part of this film because he looked upon me as a risk, and rightfully so," Pettyfer explained.

Determined to move on from his "immature" past, Pettyfer kept to himself on set. "I didn't speak on the movie," he said. "I was scared to speak. I actually did my work and I sat in the corner and listened to music because I had been told that anything I do is wrong by reps."

Unsurprisingly, this strategy backfired on the star. "I was very insecure as a human being and that also gave me a bad rep because they said, 'Oh, Alex thinks he's f---ing better than everyone else because he doesn't speak to anyone,' and that's not true. I was just genuinely nervous and scared to be myself," Pettyfer said.

The biggest celebrity feuds

However, the biggest blow to his relationship with Tatum came after filming finished, when Pettyfer rented an apartment from a friend of Tatum's in New York. But believing he was having an allergic reaction to dust and mold in the apartment, Pettyfer and his ex-fiancee Riley Keough moved out.

"They asked for the four months' rent, which, in hand, I should have paid there and then," Pettyfer acknowledged. "What happened was my cousin passed away, his lungs collapsed and he died ... and I was devastated and dealing with family trauma and forgot about the situation, which was the apartment.

"And I all the sudden got a very negative email from Channing, rightfully so, saying, 'Don't f--- my friends. You owe money. Pay the f---ing money. Don't be a clown,'" Pettyfer recalled. "And I really took that the wrong way, which I shouldn't have, and emailed him back and said, 'Listen, I'm in a really negative situation, negative head-space, could you respect me for a moment and blah blah blah.'

"And then I just got hounded through this time of grieving for money, and by the end of it, I just basically said, 'F--- them. What is money when life is so much more. I'm not dealing with this and I'm not paying.' And I should have just paid."

But while Pettyfer, who did not return for Magic Mike XXL, takes full responsibility for his bad behavior, he still insists Tatum was merely "looking for an excuse not to like [him]."
