While the rest of the lads were most likely busy spending time with their girlfriends, a "nervous" Niall took to his Twitter on Sunday night to share his worries ahead of the concert.

"Lying in my bed , cannot sleep ! Madison square garden is like 15 hours away! A performers dream coming to life #1DinMSG," he added.

"Standin up there with my guitar in my hand and standin beside the 4 best lads ever!Is what I've dreamt about! How can I forget our band," he continued.
Niall's other bandmates were all-loved up with their other halves over the weekend, with Harry Styles spotted going for what looked like a romantic stroll with Taylor Swift, while Liam Payne reunited with his ex-girlfriend Danielle Peazer.
Harry and Liam aren't the only ones getting in on the lovey-dovey action - Louis Tomlinson's girlfriend Eleanor Calder also flew over to NYC to support the singer while Little Mix star Perrie Edwards, who is dating Zayn Malik is also expected to be jetting in.
