I don't know about you, but Niall Horan is feeling 22.

The One Direction star rang in his 22nd birthday over the weekend during the band's On The Road Again Tour stop in Massachusetts. To kick things off, his bandmates serenaded their friend, along with 60,000 Directioners, with a memorable rendition of "Happy Birthday."

BTW, Liam's vocals are so on point.

Later in the night, Niall seemed to get caught up in the moment, and maybe the fact that he was turning one year older, because he decided to treat the fans to a little rendition of Taylor Swift's song all about feeling "22."

Niall started out the cover strong, but admitted that he "didn't know the words" to T. Swift's hit. Either way, it still sounded great.

HBD, Niall!
