One Direction were "gutted" 'Steal My Girl' didn't make it to number one in the UK.
The group saw their latest single peak at number three last month and though they were upset not to top the singles chart, they think Meghan Trainor's 'All About That Bass' deserved to take the number one position.
Louis Tomlinson said: "'Steal My Girl' didn't go to number one and we were gutted to be honest.
"But that's just the way it is - there's tough competition out there. 'All About That Bass' is just a monster."
Niall Horan added: "I'm all about that bass."
Despite their disappointment, the 'You & I' group - which also features Zayn Malik, Liam Payne and Harry Styles - never fail to be astonished by the support of their fans.
Louis told Britain's OK! magazine: "Everything we do, the fans are so incredibly supportive. Going into an album you think, 'We've had such incredible support over the past three albums, surely this won't be received on the same level. But they do."
Zayn added: "That's why it amazes us even more, because it's persistent."
