Bryce Harper uses Bieber as walk-up song

Bryce Harper, the 19-year-old Nationals phenom and rebuffer of clown questions, recently gave a nod to another young phenom, 18-year-old Justin Bieber.

YouTube user lfahome captured Harper walking up to the plate Tuesday night as Bieber's new single "Boyfriend" soothed the Nationals Park crowd.

The D.C. Sports Bog suggested that maybe Harper had lost a bet, but perhaps he's just a big fan of fondue, as Bieber noted in the lyrics:

I got money in my hands that I’d really like to blow

Swag swag swag on you

Chillin' by the fire while we eatin' fondue

I dunno about me, but I know about you
