One Direction recently cancelled their Belfast shows because Liam Payne reportedly had a backstage meltdown.
According to sources, the pressures of fame and being on the road for two years have made the 22-year-old singer ill, the Mirror has reported.
Insiders added that Payne was devastated about letting everyone down, especially the fans, but he wasn't physically able to get on stage so he had a complete meltdown.
Apologising to his fans, Payne tweeted, "I'm so sorry to everybody I disappointed last night. I'm feeling better now. I really hope everyone can make the rescheduled date on Friday.
