The band consisting of Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson, recently performed in New York but despite having trainers in their hotel, the teen millionaires sent a private jet 7,000 miles to bring Jarvis, reported Daily Star.
"They wanted him to get on the next plane, so they laid on a jet for him. It's incredible how much they want to build up their bodies," Jarvis's manager, Ramzy Khachnik, said.
"They haven't trained for the last couple of weeks and are feeling edgy and uncomfortable. The One Direction film is going to be a box-office hit and they didn't mind splashing out to get him there. The lads have told Mark he's crucial to their future," he added.
