The rapper opened up to Seventeen magazine, saying that it was "a different creative change of heart" that forced her to cancel the dates.
"I want to start totally anew, and if I stayed on my tour, that would mean I wouldn't even be able to start working on that until after Christmas," she said.
And while some may be speculating that it was exhaustion or stress that may have played a role in the cancellation, Iggy assured the mag that it didn't, but she did acknowledge that she "deserves a break." The "Fancy" rapper also revealed that she couldn't find any opening acts for this tour.
"I've been going non-stop for the past two years, nearly every single day. I'm not in a bad place. I think sometimes when you say you need a mental break, people are like, 'A mental break? Be sure you don't have a breakdown because you're sad.' No, not necessarily," she said. "It's very emotionally draining to be on all the time and going all the time, planning all the time."
She continued, "It's a lot, and it's tough. I need a break from everything to just enjoy what I worked so hard for, and I don't really feel like I've had a chance to do that. I need a break to figure out what I want my sound to progress to, and I need a break to figure out how I want my visuals to progress."
Iggy, who first postponed this tour back in March due to production delays, may be taking this break time to not only plan her upcoming wedding to fiance Nick Young, but to work on new music, which she hopes to release next year.
"It can kind of wear on you, too, when you've been doing the same material for a really long time. Even though a lot of people just discovered it, I am a musician and a creative person and I want to be able to perform new stuff and do new things," she said. "I feel like I'm at the end of an era now. To go on a tour in late September and to stay in that mindset of what I'd envisioned for that tour, I feel like that would stifle me."
And while she admits that she didn't want to disappoint her fans, who found out of the cancellation through an email, she knew that this was "the best thing for me."
"There are people thinking it's me giving up, or me failing at something, somehow. I said to a friend the other day, 'The only reason why at this point I would stay and do this tour is to save face publicly, or to not endure publicly what people will say if I cancel it,'" she said. "And that's not a good enough reason to do something. So that's the choice I made."
