May 3 (UPI) -- Grammy winners Post Malone and Barry Manilow announced this weekend they are canceling numerous upcoming concerts.

"Looking at the upcoming schedule after stagecoach, I came to the realization that what we were trying to do, and what's possible, isn't really lining up," Malone said on his Instagram Story Friday.

"Truth is, I promised y'all beautiful people new music, and I don't have the time to finish it before tour starts," he added.

"We ain't ready for tour just yet, so I'm making the decision to push the tour back about 3 weeks to get this music done. That being said, I'm so sorry to the folks who were planning on coming to the few canceled shows. I was looking forward to going nuts with y'all."

Malone hopes that postponing the dates on his Big Ass Stadium Tour Part 2 -- some of which were to also feature Jelly Roll -- will give him the time he needs to complete his next album, The Eternal Buzz.
