Justin Bieber Pays Homage to Biggie, Freestyles Over 'Who Shot Ya?'

Young Biebs just keeps on killing the compeition.

While on ot Hot 97.5 in Vegas with DJ Bootleg Kev, Shawty Mane went in over Biggie's classic "Who Shot Ya." What this better than his "Otis" rhyme?

We’re not going to lie, though, Biebs freestyle was pretty impressive. Still, we couldn’t help but wonder if someone did ghostwrite his rhymes.

Who could be the mastermind behind the JB's rap?
