UFC star Julianna Pena had a very curt response to Conor McGregor’s latest Twitter rant

It's difficult to know for sure, but our gut feeling is that Julianna Pena isn't the biggest fan of Conor McGregor.

In case you missed it, the Notorious was tweeting yesterday. Considering all the hubbub he's been causing with his social media activity of late, his tweeting has been causing a lot more discussion than usual. https://twitter.com/SportsJOEdotie/status/727158510094573568 First he revealed his intention to retire from fighting on Twitter, then he announced his return to fighting. Somewhere in between Dana White and his merry band of Zuffa big wigs booted him off UFC 200's main event against Nate Diaz for refusing to show up to the press conference promoting the event in Las Vegas, as it clashed with the beginning of his training camp. On Bank holiday Monday a tweet suggesting that Nate Diaz's more bulky physique should be a warning to the featherweight champion that he has no business fighting again at welterweight was enough to set the Dubliner's thumbs off. https://twitter.com/TheNotoriousMMA/status/727146193617346560 https://twitter.com/TheNotoriousMMA/status/727156559546081280 One person who appears to be fed up with McGregor's antics is top women's bantamweight contender Julianna Pena. The TUF 18 winner is schedule to take on Cat Zingano at UFC 200, and she let the Notorious know exactly how she felt about the Notorious' latest Twitter rant with one four-word tweet. https://twitter.com/VenezuelanVixen/status/727180215353413632 Harsh.
