Eminem vs. Justin Bieber, Hilarious 'Mockingbird' Remix Parody Goes Viral On Vine Before 'Shady XV' New Album Release, Daughter Hailie Jade Scott Mathers A Fan? [WATCH]

Eminem and Justin Bieber probably don't have much in common - but apparently, the "Boyfriend" crooner is a pretty big fan of the Detroit emcee. The Biebs tends to cover several Slim Shady songs at live concert events:

Wonder if the "Rap God" approves? The 41-year-old "Lose Yourself" star can't be too big of a hater - his teenage daughter Hailie Jade Scott Mathers is apparently a loyal Belieber!

Ha.

Anyway, since it's Friday, MstarsNews has a fun Vine video gem for readers...

A parody spoof of Shady's hit 2004 song, "Mockingbird" - featuring Selena Gomez's on-and-off again beau, of course!

Hey, pretty funny, right?

The clip was posted by a fan back in July, but is just starting to go viral on the web now.

The Encore tune was actually written for "Baby Jade" - interesting connection.
