Conor McGregor and Nate Diaz are just days away from facing off in the octagon for the second time in their careers, and the bad blood keeps flowing.
The headlining fight for UFC 202 took a turn for the worse yesterday when McGregor and Diaz started throwing bottles of water at each other in front of a stunned crowd in Las Vegas.
The Irishman had walked into the press conference half-an-hour late, and naturally, made no apologies for his tardiness.

Diaz simply got up and walked off after about two minutes of the pre-fight press conference - or 32 minutes, depending on whose watch you go by - and he was also the first man to throw a bottle.
So what rattled the 31-year-old so much that he had to leave in such an aggressive fashion?
"Like I said, that guy [McGregor] walks in like he was the show," Diaz said of McGregor. "But I thought the show was over, so I left the show."
McGregor was probably trying to get into Diaz's head by making him wait, and the Notorious One might see his opponent's tantrum exit as a success.
Many journalists in America believe that Diaz is the favourite to beat McGregor again after he submitted the featherweight champion at UFC 196 back in March.
This fight will take place at welterweight once again and Diaz thinks nothing has changed since the first time around.
"It's the same thing man," he said. "It's the same guy versus the same guy, it's whatever, I don't care."
Whether you believe the press conference bust-up was staged or you think McGregor is playing mind games with Diaz, one thing is for sure: Saturday is going to be a war and the Irishman's legacy will be seriously stained if he cannot exact revenge on his American foe.
