Cher has revealed she wasn't happy with Burlesque, saying she "didn't like" her performance in the film.
The 67-year-old singer and actress played a burlesque club owner in the Golden Globe-nominated musical film, alongside Christina Aguilera in her film debut as an aspiring singer and dancer wanting to make it big.
She added: "What, I don't have a brain? I'm old but I'm still pretty on top of everything."
Burlesque, which was released in 2010, was nominated for the Golden Globe award in the best motion picture - musical or comedy category while Cher's song You Haven't Seen The Last Of Me, written by Diane Warren, won the Golden Globe for best original song.
Cher, who releases her 25th album Closer To The Truth on October 14, previously complained in 2011 that the track missed out on an Oscar nomination, despite it scooping a number of gongs.
