“You Snaggle-Toothed Grammar Holocaust”: Frankie Boyle Lets Rip At One X Factor Finalist On Twitter

Oh, Frankie Boyle’s been bold before…

But this time nothing held him back.

The controversial comedian had an three-day Twitter row with X Factor finalist James Arthur.

The solo singer, 24, hit back after getting fed-up of reading the 40-year-old Scot's offensive tweets about him and the ITV show.

After Frankie likened him to a 'tramp', James tweeted: “Poor old man making yet more s**t jokes about X Factor because he knows that's the only way he can get attention any more #prat.”

But it was just fuel to the fire as Frankie was quick to fire back: “I think if I wanted attention I'd sing covers on a talent show, inked up like a schooldesk in a remedial class.”

Oh, that was it!

Soon the pair were battling with each other in a tit-for-tat argument on the micro-blogging site.  

Frankie pulled up James on his spelling mistakes, replying: '"apposed"? I hope you didn't spell your own tattoos. I also hope Simon's (Cowell) demonic j**z boils through your vocal cords.'

Unimpressed with Frankie's crude reply involving X Factor boss Cowell, James wrote: “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 [sic].”

Frankie even continued the argument into yesterday, phew, by hitting out at James's looks: “James Arthur looks like someone put a sheep's teeth into a baby's head #Xfactor...”

Oh, harsh.

Who started it? Frankie, of course.
