According to tabloid reports, the 'Not Fair' singer is said to be '80 per cent confirmed' for a role on the UK series - taking over the position left open by Simon Cowell or Cheryl Cole should they choose to focus on the American version.
"Nice to know that I'm 80% confirmed to be a judge on X Factor," Allen wrote on Twitter. "Anyone thinking about running it by me? maybe that's the 20% bit. (sic)"
She quipped: "I'll only do it if there's a 'pop songs in a foreign language week'." The 25-year-old went on to link to an Italian version of Stevie Wonder's 'My Cherie Amour', adding, "like that".
Last month, it was suggested that Allen held talks with ITV and had been offered a six-figure contract to join the programme.
Presenter Dermot O'Leary has given the singer his backing, saying that he would "love" her to fill Cowell's position.
