Harry Styles' new Rolling Stone interview is here – and jam-packed full of candid details regarding his next album, the future of One Direction and his experience on psychedelics.

In it, the 25-year-old singer, who made headlines this month after appearing shirtless on the cover of the magazine's September issue, not only revealed that his highly-anticipated second solo album is "all about having sex and feeling sad" but he admitted doing mushrooms helped his creative process.

“We’d do mushrooms, lie down on the grass, and listen to Paul McCartney’s Ram in the sunshine. We’d just turn the speakers into the yard. You’d hear the blender going, and think, ‘So we’re all having frozen margaritas at 10 a.m. this morning," Styles explained before recounting the story of when he accidentally bit off the tip of his tongue.

"This is where I was standing when we were doing mushrooms and I bit off the tip of my tongue," he shared. "So I was trying to sing with all this blood gushing out of my mouth. So many fond memories, this place.”

Elsewhere in the interview, Styles also revealed whether he thinks he'll ever reunite with his 1D bandmates.

“I don’t know. I don’t think I’d ever say I’d never do it again, because I don’t feel that way. If there’s a time when we all really want to do it, that’s the only time for us to do it, because I don’t think it should be about anything else other than the fact that we’re all like, ‘Hey, this was really fun. We should do this again,'" he said.

"But until that time, I feel like I’m really enjoying making music and experimenting. I enjoy making music this way too much to see myself doing a full switch, to go back and do that again," Styles continued. "Because I also think if we went back to doing things the same way, it wouldn’t be the same, anyway.”

He said that even though he's not as close to Zayn Malik, Niall Horan, Liam Payne and Louis Tomlinson, they'll always have the memories. "We did this really cool thing together, and we’ll always have that," he explained.

The British heartthrob also shared his thoughts on feminism and why it's so important for people to understand that the movement is about equality, not the preconception that women think men "should burn in hell."

“I think ultimately feminism is thinking that men and women should be equal, right? People think that if you say ‘I’m a feminist,’ it means you think men should burn in hell and women should trample on their necks," he said. No, you think women should be equal. That doesn’t feel like a crazy thing to me."

"I grew up with my mum and my sister — when you grow up around women, your female influence is just bigger," Styles added. "Of course men and women should be equal. I don’t want a lot of credit for being a feminist. It’s pretty simple. I think the ideals of feminism are pretty straightforward.”
