Niall Horan

Niall Horan may have officially kicked off his "Flicker Tour," but he made a special stop in Las Vegas during the 2017 iHeartRadio Music Festival, returning to the stage as a solo artist. The 24-year-old pulled double duty performing earlier in the day at the Daytime Village presented by Capital One, and again later in the night at T-Mobile Arena. 

During his set, Niall performed some of his new solo music including his debut single "This Town," his new single "Too Much To Ask," "On The Loose," and his now No. 1 single "Slow Hands."

It's safe to say Niall completely melted our hearts throughout the weekend, and here are all of those adorable moments.
