Alex Pettyfer is getting candid about his less than friendly relationship with his Magic Mike co-star, Channing Tatum.

The 25-year-old actor appeared in the 2012 film directed by Steven Soderbergh, but did not take part in its sequel, 2015's Magic Mike XXL. Pettyfer claims that he and Tatum didn't part on good terms in a new interview for writer Bret Easton Ellis's podcast, B.E.E., and also takes most of the blame.

"It’s true," Pettyfer says of reports that the two didn't get along. "Because Channing Tatum does not like me -- and for many reasons [and] many being my own fault."

The British actor claims Tatum, 35, wasn't sold on casting him in the first place because of his bad boy reputation -- which includes an infamous 2011 VMan magazine interview in which he called Los Angeles an "insidious pool," and claimed he had "thank you" tattooed above his crotch "in case [he] forgets to say it" -- but was convinced by Soderbergh that he was right for the part. Pettyfer says his own insecurities led him to not speak on set, which gave him a misunderstood reputation among his castmates.

"I was scared to speak," he recalls. "I actually did my work and I sat in the corner and listened to music because I had been told anything I did was wrong by my reps. I was very insecure as a human being. That also gave me a bad rep because everyone was like, 'Alex doesn't speak because he thinks he's better than everyone else.' That's not true. I was just generally nervous and scared to be myself. I was in character."

However, he says the straw that broke the camel's back was when he didn't pay one month's rent on an apartment that was owned by a friend of Tatum's. Pettyfer says he was staying there with his ex-fiancee, actress Riley Keough, but claims he "couldn't breathe" because of being highly allergic to what he believes was mold and dust in the apartment. After the two left the place, he says they were asked for the full month's rent, but he "forgot" about the situation after dealing with his cousin's death.

"All of a sudden, I got a very negative email from Channing -- rightfully so -- saying, ‘Don't f**k my friends. You owe money. Pay the fu**ing money. Don't be a clown,'" Pettyfer claims. "And I really took that the wrong way, which I shouldn't have, and emailed him back and said, 'I'm in a real negative headspace and can you respect me for a moment and blah, blah, blah.’ And I got hounded through this time of grieving for money."

"By the end of it, I just said, 'F**k them, what is money when life is so much more. I'm not paying,'" he explains. "And I should have just paid. I think he was looking for an excuse to not like me."

When the two met up again for reshoots, Pettyfer claims Tatum had told everyone he didn't like him.

"What Channing says goes," he says. "He's a movie star. I made the poor decisions."

Still, in hindsight, he says he learned a valuable lesson on growing up from Tatum.

"Channing was actually an incredible influence on me because after this whole situation happened -- this was kind of the end of my immaturity and all my experiences put into one -- and Steven Soderbergh was a huge part of that as well and I owe my life to that man," he reflects. "It was an incredible experience making Magic Mike. I wouldn't replace it for anything."
