Nobody thought Nate Diaz would defeat Conor McGregor at UFC 196 ? and that includes Floyd Mayweather's best bud, Justin Bieber. Despite making the jump from Featherweight to Welterweight, McGregor was the heavy favorite against Diaz heading into their Saturday night fight. However, Diaz proved to be too much for McGregor to handle when he served "The Notorious" the first defeat of his UFC career by submission in the second round. That prompted many to take shots at McGregor for talking the talk but not walking the walk, while others ? like Bieber ? were left piecing their broken hearts back together. Bieber posted on Instagram saying, "No bandwagon but Conor is a true champion, fights with style and finesse, all the respect to Nate but his style is terrible. Nate has crazy heart respect." The good news for Bieber? McGregor promises he'll be back soon.
