The official 5SOS Twitter account shared the crummy news, writing: "So Mikey lost his passport :( That means he cant fly to the UK & has to stay in the US, so were playing #CapitalJBB as a three piece today."
It sounds like Mikey needs a passport babysitter.
The band also shared an apology, tweeting: "We're really sorry to everyone expecting to see the four of us on stage, we're still gonna rock out so get ready to party! @CapitalOfficial."
Capital FM tweeted about the sad news as well and shared a video from Michael, where he calls himself "really stupid" for losing the passport, adding, "I'm so sorry I can't be there." The show went on, but Michael was definitely missed!
