The former One Direction singer, 23, was soon trending after releasing “sexy” new track, Slow Hands.
Horan unveiled the track on Twitter with a 20 second snippet.
He captioned the post: “I've been waiting a long time for you to hear this song. Hope ya love it!”
The catchy song had fans swooning over the lyrics which included: “We should take this back to our place/ ‘cause I want you baby.”
Horan was described as a “blessing” and his voice “freaking sexy” as fans tweeted their love for the track, including The Vamps' James McVey who tweeted: “Great vibes from @NiallOfficial with #SlowHands. Some great music about at the moment and this is certainly a welcomed contribution.”

Horan said he wanted the song, which is about being in a bar, to be “cheeky”.
Speaking on Siriux XM Hits 1 he said: “The whole song was pretty off-the-cuff. I wanted it to be a little bit cheeky with the lyric. We wrote this concept about being in the bar. The first line of the song is ‘We should take this back to my place‘ – usually that’s what the guy would say, but we flipped it that the girl would say that, and that’s what she said right to my face.
“With the song, before we even wrote lyrics, we had this big track and it sounded quite sexy. So we thought that this concept would match the vibe of the song, and I think we might have been right.”
The single comes hours after he announced his departure from Simon Cowell’s record label to “broaden” his horizons.
Speaking to The Sun, he said: “We were very close to Simon for years and had a lot of success together. I just felt like I wanted and needed a fresh start.
“It’s a long time to be at a label I wanted to broaden my horizons and try something new.”
Horan’s former One Direction band mate Harry Styles dropped his second track since going solo earlier this week.
Titled Sweet Creature, the track had fans in tears, while others demanded he receive a Grammy Award.
