Justin Bieber Singing To A Fan On Her Birthday Will Melt Your Heart (Video)

Justin Bieber may be out searching for the most beautiful woman to ever grace this Earth, but he'll always make time for his devoted fans.

Yesterday, Justin performed a medley of his old and new songs to about 1,500 Beliebers in Toronto, Canada. During the acoustic set, Bieber pulled out all the stops.

He played piano, he sang a capella and he even threw in a cover of Drake's "Hotline Bling."

The most memorable moment of the evening, however, had to be when he serenaded this 16-year-old fan for her birthday with "One Less Lonely Girl."

Your birthday celebrations can only go downhill from here, girl.

Justin, keep making all our hearts melt. You are a god.

You can check out clips from Bieber's entire performance up top, and skip to the three-minute mark to see his adorable serenade.
