Justin Bieber arrives at the 2015 MTV Video Music Awards at Microsoft Theater on August 30, 2015 in Los Angeles, California. 

Here's one potential feud that won't end in stitches: Justin Bieber may not have known who Shawn Mendes was a few days ago, but he does now -- and he likes what he's hearing.

Earlier this week, Bieber was asked what he thought of Shawn Mendes, a rising star that has drawn comparisons to The Biebs. Bieber replied, "Who is Shawn Mendes?" Many people took it as a shady slam, while others pointed out he probably just didn't know.
