WATCH: Bryce Harper serenades young fan at Nationals Winterfest

WASHINGTON - The Washington Nationals' Winterfest draws fans of all ages to two days of meet-and-greets, games and family activities.

But for one special young fan, an extra dose of MVP fun was in order!

The Washington Nationals posted a video to their Facebook page showing National League MVP Bryce Harper serenading a young fan on stage with a rendition of "My Girl."

The adorable clip shows Bryce down on one knee (cue the ladies swooning!) and the cute little girl dancing and waving along to the music.
