Niall Horan is feeling "completely mind blown" after his debut solo LP 'Flicker' reached number one in the US.
The 'Slow Hands' singer reached out to thank his fans and his team for sticking by him throughout the making and promotion of his record and to reflect on the "crazy" few years getting the chart-topping record released.
In a lengthy note to his 35.5 million followers, Niall posted on Twitter on Sunday night (29.10.17): "Wow! Thank you so much. My mind is completely blown.
"An album that I wrote has gone to #1 in the United States and I cannot thank you guys enough for supporting it.
"It's been a crazy couple of years for me between writing, recording and promoting this record.
"Today it really feels like all of the hard work has paid off.
"Huge thanks to my label and management for the constant support on everything I do.
"My band have been amazing. Travelling around on every TV show and every radio thing with me this year helping me achieve this.
"The fans. You are incredible! The love I get on a daily basis is amazing. Thank you and thank you again.
Love Niall (sic)"
With Niall's record topping the US chart, and his One Direction bandmate Harry Styles and ex-member Zayn Malik also nabbing the number one spot with their debut albums, the boyband continue to make history.
The trio have matched The Beatles record as a band with three solo number one records between them.
However, despite their solo success, Niall recently reassured fans that he's definitely up for reuniting with One Direction - also comprised of Liam Payne and Louis Tomlinson - and insisted the boys would be "stupid not to" reform.
The Irish pop star said recently: "[We'd be] stupid not to ... I'm up for it, yep, 100 per cent, I've said that on multiple occasions."
The 'Too Much To Ask' hitmaker would never distance himself from his boyband past because he knows he wouldn't have ever got the opportunity to make his record if he hadn't been a member of 1D.
Speaking about his pride at being part of the group, he said: "I wouldn't be here if it wasn't for it."
Although Niall is keen to reform One Direction in the future, he has previously stated he doesn't think it will happen in the near future because the boys are all busy with solo projects and were exhausted by the time they headed off to pursue other projects.
He previously said: "We were knackered by the end of One Direction ... I wouldn't stick a date on it."
