We're not crying, you are.

Harry Styles took the stage at Capital's Jingle Bell Ball in the UK over the weekend, and the crooner had a little surprise up his velvet sleeve for his OG One Direction fans.

"If you know the words to this one, please do sing along," he told the crowd before delving into a rock 'n roll rendition of the song that started it all, "What Makes You Beautiful." And that's just what the crowd did. Mixed with screams of excitement, the audience sang loudly along to the 2011 smash hit that launched Styles and his 1D bandmates into superstardom.

The performance comes just one week before the release of Styles' sophomore solo album, Fine Line, out on Friday (Dec. 13).
