Watch: Conor McGregor and Jose Aldo get into a heated exchange and have to be separated

Is it safe to say at this point Conor McGregor and Jose Aldo aren't friends?

The fighters appeared at UFC's Go Big press conference earlier this evening, and got into a heated exchange when facing off. McGregor, the UFC Interim Featherweight Champion and Aldo, the Featherweight champion, are due to finally fight at UFC 194 in December in a unification title bout. https://twitter.com/ufc/status/639904341323816960 Aldo then had to leave the press conference early, because he was due to attend a wedding, which McGregor seemed to find bewildering. https://twitter.com/MMAHistoryToday/status/639906538329612288 McGregor said he doesn't believe Aldo will show up for the December bout, and told the other fighters on stage, who weigh between 145 and 170lbs, to prepare for the fight. Earlier in the press conference, McGregor also took aim at UFC Lightweight Champion Rafael dos Anjos, who said a fight with the Notorious would be "easy money". https://twitter.com/ufc/status/639898393058263040
