Niall Horan would be a "lost soul" without his fans

Speaking on the red carpet at the Microsoft Theater, he said: "I'm looking forward to this. This is a show that [One Direction] had success at back in previous years, and had some good performances and had some great nights at, and I'm looking forward to making a few more memories...

"If you didn't have the fans in there, I would be a lost soul. It's great though. [1D] got to perform in front of such great crowds, and this [solo] one will be no different, I imagine."

Though Niall admitted it was "different" attending the glamorous bash on his own, he was still enjoying himself without Liam Payne, Harry Styles and Louis Tomlinson by his side.

He told 'Entertainment Tonight': "That's the thing I been asked a lot today.

"It's obviously different, buts it's different because there's no one else around, but I've been enjoying it so far, the performances that I've done and it's been fun and yeah I just really enjoyed it."

And the 'This Town' singer was looking forward to catching up with former bandmate Zayn Malik - who quit the group in March 2015 - as they haven't spoken "in a few months".

He said: "I haven't spoken to him in a few months or whatever, and haven't seen him in a while, so I'm looking forward to seeing him."

But Niall remains in regular contact with the rest of the 'History' group.

He told E! News: "I was talking to the boys recently, and yeah, we're big on the e-mail chat the old e-mail thread. Everyone is great.

"Everyone is just kind of enjoying their time, you know, just chilling and doing their own bits and pieces."
