Sheamus goes one-on-one with UFC star on Twitter

Fast rising Irish UFC star Conor McGregor appeared on SI Now today, which you can watch above. During the interview, McGregor was asked about fellow Irishman Sheamus, and McGregor said that he would whoop Sheamus' ass. That prompted a Twitter war between the two stars, which you can check out below:

Sheamus: "ok @SInowLIVE @ufc @TheNotoriousMMA, Conor wins. I don't hit featherweights or shoeshine boys. Mouth off to @BrockLesnar fella, I'm injured... Had bigger dumps after a salad @TheNotoriousMMA lad. U can hold @BrockLesnar's @WWE title while the big boys duke-it-out. Win @ufc title 1st"

McGregor: "@WWESheamus, @BrockLesnar fought PURE, phoney. Me and Brock Vs You and any shmuck of your choice. #CelticPhoney #TagTeam @JRsBBQ @WWE @UFC"

Sheamus: "Phoney? @TheNotoriousMMA @BrockLesnar @WWE @ufc haha that last lad you 'knocked-out' went down on the breeze of a punch... #NeverConnected"

McGregor: "Careful now scaldy, you will wake up with no teeth and your nose on my mantle. #CelticPhoney #NeverFought... 'Never connected' sounds more like your game. You wear ball stranglers and slap mens asses for a living."

Sheamus: "Whereas you talk for a living son & we all know who's ass @TheNotoriousMMA is kissing nightly. #LittleManBigChip"

McGregor: "@WWESheamus I'll whoop you at your own game, then we can toast a whiskey and talk about true fighting. Always remember #UFCAsRealAsItGets"

Sheamus: "Whiskey in Dublin this Christmas @TheNotoriousMMA. Shirts on the deck, back-to-back, and we'll fight everyone. #TraditionalIrishChristmas"
