Harry Styles and his bandmate Zayn Malik stayed in Los Angeles to party for an extra day after the American Music Awards.
Sticking in the city to celebrate their hat-trick of awards, the rest of the group - Niall Horan, Liam Payne and Louis Tomlinson - all made their way to Sydney for their appearance at the ARIA Awards.
Harry and Zayn touched down in the country just in time to join their bandmates on the red carpet, but Niall has now revealed the reason behind their late arrival.
Speaking to Australia's Kiis FM he explained: "What happened there was, we'd just won three American Music Awards, and some people wanted to get straight to Australia and Harry here wanted to have a little party in Los Angeles."
Agreeing with his friend, Harry also claimed he had been suffering with earache and so didn't want to make it worse by getting on a flight.
"I also didn't feel very well so I didn't want to fly. I wanted to wait out the storm to fly. My ear hurts."
The singers went on to open up about having their underwear stolen on their last trip to Oz, when a fan pinched a pair of Liam's boxer shorts from his hotel balcony.
Harry joked:"Now we leave them out as bait, we just leave pants around everywhere and set traps."
He added that the group had all also been sent a pair of personalised Speedo swimming trunks with their names emblazoned on them.
"I actually got a Speedo with my name on it. I've got mine on right now."
