The 28-year-old star, who enjoyed a successful few years as a judge on 'The X Factor' and a short-lived stint on the American version of the series last year, said that she is not likely to work with the talent show boss again, reported BBC online.
"In my mind it's years ago, but people keep talking about him. It doesn't matter where I go, what interview I'm doing, people want to talk about Simon. I don't really even think about Simon, doesn't really come into my brain," Cole said.
The singer also said that her music career is her priority right now and that her new album 'A Million Lights' is her most varied yet.
"It's got a R&B influence, there's actually some dub step sounds on there, I know a lot of people hear that as noise, but I really like that feeling. Wills (Will.I.Am) is on there, Wretch 32's on there. It's got some dance feel, it's got some ballads and it's got some dubs," she added.
