Zayn Malik stepped on stage in Las Vegas wearing a bandage on his arm this weekend.
The singer, who's on a headline tour of America with One Direction, prompted a string of worried Tweets from his admirers.
'Omg please don't tell me Zayn has a cast on his arm. omg i'm gonna cry.. @zaynmalik ARE YOU OKAY BABY? :"(,' Tweets a fan.
Another writes: 'What the hell did he do!!??'
Fortunately 19-year-old Zayn's injury wasn't too serious - he'd reportedly suffered a strain during a work out.
Zayn's is just the latest in a long line of 1D accidents - Liam Payne recently broke his toe after losing control of his laptop.
'Dropped a computer on it,' Liam, 18, replied to a fan who asked him how he hurt himself.
