One Direction are probably the busiest little bunnies in pop, so it's hardly surprising that they'll take any opportunity to catch some well deserved zeds.
And after a very hectic day yesterday, the lads did just that as they travelled back from a promotional trip to Paris.
The boys all curled up for a nap on the Eurostar last night, and Harry posted the sleepy pics on Twitter of his fellow bandmates having 40 winks in the first class carriage.
"It's been a tired train back," he tweeted before posting the snaps of Louis, Zayn, Niall and Liam.
They were up at the crack of dawn to celebrate Radio 1 DJ Chris Moyles' birthday, making an appearance at the station's Madia Vale studios for the bash, before hot footing it across town to catch the train to Paris for their day trip.
They came back home last night ahead of tonight's Brit Awards, where they are nomiated for Best British Single for What Makes You Beautiful.
And while we knew One Direction mania had already spread as far as the States, their French fans are clearly something else, as they turned out in their hundreds to catch a glimpse of the boyband.
But despite being used to an army of adoring fans mobbing them wherever they go, the boys were left surprised by the scenes at Paris' Gare Du Nord.
The had to grab on to bodyguards as they made their way through the crowds, and French police were there to ensure the crowds were kept under control.
One Directioner Niall was left particularly shaken by the scenes and admitted he is uneasy in large crowds.
"These things happen. Part of what its about. It was really cool today in Paris, and as directioners always do, come out in hundreds," he tweeted. "If I ever look nervous its coz i hate tight spaces. But don't worry, it's all cool on my ends."
His bandmate Liam also lost a shoe in the craze, and while the whole incident may seem dramatic, the pictures make for a great Tuesday afternoon game of 'Where's One Direction?'
