One Direction star Niall Horan has been spotted using crutches to walk and reveals he has had "major surgery".
The 20-year-old Mullingar native had the operation earlier this month to correct a long-standing problem with his left knee ahead of the band's next tour in May.
On Thursday (January 16) he was spotted arriving at Heathrow Airport in London. He then hobbled to his waiting car with the aid of crutches.
He later confirmed via Twitter that he had undergone "major" surgery but was quick to assure worried fans that he is on the mend.
