Being boys, One Direction have probably been living off a diet of pizza and Pot Noodles as they tour America.
So their mums will be pleased to hear they have been treated to a decent, square meal courtesy of fellow Brit Gordon Ramsay.
The boys dropped into see Gord at his steak restaurant in Las Vegas, where he cooked up a storm for Louis, Niall, Liam and Harry.
Gordon shared a picture of himself with the lads on Twitter, writing: "@onedirection having a bite @ramsaysteakLV before their gig !!"
And one member of the band in particular who was grateful for a freebie meal was Niall Horan, who tweeted the chef to say thanks.
"@GordonRamsay01 great to meet ya today dude, thanks for the steak, been waiting for food like that for a long time! Musch appreciated!(sic)" he tweeted.
