The singer made the admission while defending criticism from fans who are now questioning the validity of her previous 'Farewell Tour', which ran between 2002 and 2005.
Mocking the star's recent revelation that she will embark on another tour in September, a 'fan' tweeted: "true farewell tour will be when you're on your deathbed?"
Cher responded: "THIS 1 WILL B "LAST ONE"! I WANT 2 DO IT "WELL" JUST 1 MORE TIME! NITE (sic)"
The new tour will be in support of the performer's upcoming 26th studio album, which she started recording last year.
The record will feature a duet with Lady GaGa called 'The Greatest Thing', which was produced by RedOne.
