Charli XXC and Bleachers' "Charli and Jack Do America" tour may have been a match made in music heaven, but as of today (Aug. 21), the honeymoon is officially over. Both artists announced via Facebook that the second leg of their joint U.S. tour has been cancelled.

"I have some bad news," Charli XCX announced to fans via Facebook. "For personal reasons I will not be able to continue this tour," she explained. "These personal reasons include the fact that I need to be creative... I am struggling to create whilst I'm on the road and that is making me unhappy."

Bleachers' Jack Antonoff made his own statement, emphasizing his love and respect for Charli. "I love Charli. She's my friend and I respect her as a person and as an artist," he wrote. "Was all geared up for leg 2 of the tour when we got a call from Charli's camp that she couldn't continue on the tour. Came as a bit of a shock to me as I'm sure it is to you right now."

Despite attempts to carry the rest of the tour on his own, Antonoff expressed that "reworking the tour at this late stage without Charli is not realistic."

Whatever's going on behind the scenes, hopefully both Jack and Charli will collaborate again soon. Check out full statements from both artists below.
