UFC featherweight champion Jose Aldo and interim champion Conor McGregor came close to blows at a UFC press conference in Las Vegas.

McGregor and Aldo faced off in front of UFC president Dana White, but were dragged away from each other by security guards.

WE’RE RICH, BABY. CONOR MCGREGOR MADE US RICH. BREAK OUT THE RED PANTIES.

“The Notorious” Irishman didn’t stop there, taking pot shots at everyone from Chad Mendes to Donald Cerrone and UFC lightweight champion Rafael dos Anjos.

McGregor will get a second shot at Aldo’s belt on 12 December and should he win, he hinted that a move into the lightweight division was on the cards.

“I’m the money fight in all weight divisions,” McGregor said.

Jose Aldo was having none of it.

“I think he’s a clown,” he said. “I’m really sorry that I couldn’t fight him the last time and when it comes time to fight him now, I’ll kick his ass.”

McGregor also had a few words for current UFC lightweight championship Rafael dos Anjos, who will defend his title against Donald Cerrone on 19 December.

Responding to a question about whether Dos Anjos would rather fight McGregor and not Cerrone, McGregor said of course he would.

“I can make you rich,” McGregor said.

“I can change your bum life. You fight me, it’s a celebration. When you sign to fight me, it’s a celebration. You ring back home, you ring your wife. ‘Baby, we’ve done it. We’re rich, baby. Conor McGregor made us rich. Break out the red panties.”

The “Go Big” press conference was held at the MGM Grand in Las Vegas to promote the UFC’s upcoming slate for the final quarter of 2015.

As part of its “Go Big” campaign the promotion will hold a historic three back-to-back events in December.

“We have all these great fights happening in December, and we started looking at the end of the year, and a lot of other people needed fights, so we said let’s do three in a row,” UFC president Dana White said.

“It’s a killer weekend in Vegas right before Christmas, and we’re gonna do it.”

A co-main event for UFC 193 in Melbourne was also announced, with a women’s strawweight clash between champion Joanna Jedrzejczyk and Canadian contender Valerie Letourneau.

“This whole women’s thing is so crazy right now; it’s on fire,” White added. “Joanna is our little rockstar too, so we decided to do Ronda and Joanna together, defending their titles in Melbourne.”

White also confirmed the date for the historic UFC 200 event, as the 2016 edition of International Fight Week will culminate with the card at the new Las Vegas Arena on Saturday, 9 July.
