Niall Horan recently reflected on four years as a member of One Direction. Along with Harry Styles, Liam Payne, Zayn Malik, and Louis Tomlinson, he has been part of one of the most successful boy bands in decades. The band met on the U.K. version of The X Factor, and while they didn’t emerge as the season’s top act, they signed a record deal shortly thereafter, so they were winners in their own right.

During an interview with MTV, Niall admitted that he and his fellow band members were feeling a bit sentimental about reaching their four-year milestone. He also admitted he went a bit crazy posting on Twitter as a result.

Niall’s first tweet reflects on the anniversary.

Wow ! Can't believe it! 4 years ago today we were out together ! Crazy how time flies but it also feels like it was years and years ago !

Can you believe that four years have passed since Niall Horan, Harry Styles, Liam Payne, Louis Tomlinson, and Zayn Malik first appeared on the music scene as One Direction? Their first big hit, “What Makes You Beautiful,” still gets some air time even four years later.

Amidst romance scandals and rumors of a split, One Direction is still going strong. It’s clear that Niall Horan is quite grateful for the life the band’s success has afforded him.

Can you blame him?
