Katie Hopkins has accepted Ellie Goulding's challenge of a charity boxing match.
The outspoken media personality and the 29-year-old pop star recently became embroiled in a Twitter spat after Katie voiced her support in favour of Italy leaving the European Union, with Ellie calling on the 41-year-old to delete her account.
Earlier, Katie posted in reference to the Italian referendum and German Chancellor Angela Merkel: "ITALEXIT!! Another one falls, welcome back to the lira. Ciao ciao to the E.U. ...how's your day going Miss Merkel? (sic)"
And Katie refused to cave in to Ellie's demand she deletes her account, replying: "Ellie. It is never going to happen. Stop talking now lovely, that pitch sets the dogs off."
Her remarks prompted the chart-topping singer to suggest they should sort out their differences in a boxing ring.
Alongside a picture of herself holding a rubbish bag, Ellie wrote: "Taking the trash out, suitably apt #ByeKatie #Fancysomesparring (sic)"
A Twitter user then suggested they should fight in aid of charity, and Ellie tweeted: "I'm so, so down. However it wouldn't make for great tv because it would be over in seconds. (sic)"
But Katie - who underwent brain surgery to relieve her epilepsy earlier this year - insisted she was up for the challenge, tweeting: "Sure @elliegoulding - you are on. I have fought far tougher things this year than some shampoo sales-bird. (sic)"
Again, though, Ellie was determined to have the last word in their spat and she posted a video of herself working on her boxing skills in the gym.
She captioned the video: "@KTHopkins Brain transplant was it? Good work! (sic)"
Last month, Ellie allegedly threatened to punch a guest after she was refused entry into the VIP section at an event in London.
The 'Love Me Like You Do' hitmaker is said to have flown into a rage after a fellow Animal Ball attendee stopped her from going into the private area of the bash, because "only VIPs could enter".
Ellie said: "I've never met anyone as mean in my life. If she speaks to me again I will f**king punch her! I swear I'm so mad."
