5 Seconds of Summer star Ashton Irwin has professed a love for Niall Horan's underwear.

The Australians have regularly supported the One Direction lads on tour.

It seems, however, that drummer Irwin has gotten up close and personal with some of the pop group's clothing.

When asked by BBC Radio 1 recently to make up a One Direction headline, Luke Hemmings said:

"I've got one - Harry Styles vomits on the side of the road and someone picks it up and sells it."

Ashton Irwin meanwhile then said: "I borrowed some of Niall's underwear once...I live and breathe in Niall Horan's underwear."

Calum Hood then revealed that he once borrowed Zayn Malik's shorts.
