Pop star Justin Bieber surprised a superfan, Lynsey Mickolas, 10 years after serenading her with the song "One less lonely girl" on stage. It was back in 2010 that the two met during a concert. The singer surprised Mickolas once more during a special moment in the finale on his YouTube docuseries "Seasons", reports dailymail.co.uk.

While Mickolas recalled her unforgettable Bieber moment, the singer prepped for another special performance. Mickolas, now a forensic chemist living in Virginia, spoke about her August 31, 2010 night at Madison Square Garden. Years after, it seemed unreal for the fan who told cameras: "To be honest, I don't remember everything from that night because everything just happened so quickly and it was so overwhelming."
