Just days performance dates were announced, a joint tour with Kanye West and Lady Gaga has been canceled.
Live Nation made the announcement Thursday but did not offer any explanation, according to the Associated Press.
The tour — titled "Fame Kills" — had been in the works for months and was set to kick off next month, on Nov. 10 in Phoenix and it was planned to run through at least January.
The news comes less than a month after West made headlines for ambushing Taylor Swift during her acceptance speech at the MTV Video Music Awards on Sept. 13.
After multiple apologies posted to his blog, he blamed not taking time to grieve over his mother's 2007 death as the reason for his outburst during an interview on Jay Leno's show.
"So many celebrities, they never take the time off," he said. "I've never taken the time off to really — you know, just music after music and tour after tour. I'm just ashamed that my hurt caused someone else's hurt… But I need to, after this, take some time off and just analyze how I'm going to make it through the rest of this life, how I'm going to improve."
