X Factor's James Arthur has found himself in a Twitter spat with comic Frankie Boyle.
Singer James hit back at the former Mock The Week panelist after he made a joke about last night's latest performance.
Frankie tweeted yesterday evening: "James McArthur is like a cross between a tramp and a duckling #xfactor."
This morning saw James reply: "Poor old man making yet more s**t jokes about Xfactor because he knows that's the only way he can get attention any more #prat"
However Frankie didn't back down, replying to James: "I think if I wanted attention I'd sing covers on a talent show, inked up like a schooldesk in a remedial class."
And James responded: "Your about as funny as aids.. Your a sad man and I can't wait to see you coz it's about time someone gave you a reality check."
Let's hope we see Frankie on the Xtra Factor sometime soon!

The X Factor 2012 live shows tonight on ITV1 and ITV1HD with the semi-final results show.
There will be performances from Pink and Tulisa as well as the final elimination of the series.
There's no sing off on this evening's results, meaning act with the lowest votes will automatically get the axe.
