One Direction's Zayn's So Vain

The One Direction lads reckon Zayn knows he's beautiful and name him the "most vain".

The No. 1 'What Makes You Beautiful' stars joined Capitalfm.com for a live webchat, and the band reveal their vainest member.

"Zayn," they all agree. "Definitely Zayn."

"I always get told I’m the most vain," Zayn told us.

"But I’m not any more vain than the other boys in the group."

But bandmate Louis begs to differ, admitting that he likes to take care of himself but not as much as Zayn.

"I would say I’m vain and I’m less vain than you so…" he added.

'What Makes You Beautiful' is out to buy and download now, with the new album expected later this year.
