Niall and the rest of the band were trying to get some sleep in New York ahead of an appearance on Good Morning America, however their female followers had other ideas.
Taking to Twitter, Niall revealed that his hotel room phone had been ringing off the hook after some mischievous girls got hold of his number.
He pleaded with them: "Please girls, I gotta be up in literally a few hours for GMA. Please stop calling my room!"
Just four hours later, Niall admitted: "It's an early one! Like a zombie right now! It must be coffee time!"
But despite being kept awake until the early hours, it seems there are no hard feelings between the Irish singer and his admirers, who had camped out to catch a glimpse of 1D.
He later added: "There is absolutely no doubt about it! We have the best fans in the world! The cold is unbelievable and u are out in thousands in the park."
