DIIV frontman Zachary Cole Smith believes that he's "fucked up" girlfriend Sky Ferreira's life. In a lengthy Stereogum interview, the musician has said that he still feels guilty about the effect their 2013 arrest had on Ferreira's career. The pair were caught with heroin and ecstasy while Smith was driving in Saugerties, New York. 

“Basically I just was stupid," he said. "I fucked up, and it was entirely my fault, and I fucked up my girlfriend’s life. She literally didn’t do anything wrong. She basically was just a passenger in the car with a person who was out of control for a minute. She got in deep shit... Her career got really fucked up because everybody thought she was a drug addict, which she’s absolutely not. That’s the worst part of it for me is that I really fucked her over.”

Smith admitted that he had an arrest warrant out for driving without a licence, and that the drugs in the vehicle belonged to him. The court has ordered Smith to attend rehab, while Ferreira was ordered to attend anger management classes. 

Ferreira lost several modelling contracts as a result of the arrest. Given that Ferreira self-financed the release of Night Time, My Time with the money from her lucrative contracts – which have included campaigns with Saint Laurent, Calvin Klein's ck One and Benetton – you might expect her to hold that against Smith. But she seems to cop to her own part in the incident: "I did lose out on a lot of opportunities, but it was my fault,” she said. “I was in the car.”

According to Smith, he has struggled with various addictions throughout his life, but described heroin as "this ultimate forbidden thing, and that makes it the most tempting thing around". The DIIV musician says he is now in recovery for his drug addiction, although he wouldn't describe himself as "totally clean and sober". 

"I wouldn’t say I’ve beaten it or anything because I don’t know if anybody can," he said, "but I’m trying my best."

DIIV is now working on a follow-up to their 2012 debut album, Oshin.
