The singer, whose debut single 'Insatiable' is due to be released on November 1, also said that she would never be a judge like Girls Aloud bandmate Cheryl Cole as she could not be mean to the contestants.
Speaking to Metro, Coyle explained: "I'm not doing Strictly Come Dancing or X Factor for this campaign. I only want to do live shows.
"What happens with TV shows is you can't always do things live. You can't really get the full effect and with 'Insatiable' being such a big song and because I'm just starting off, I want it to be all about doing stuff live."
Coyle added that she is not a big fan of The X Factor, saying: "I love the live shows when they're on and all singing great but I hate it when the judges say bad things about their singing.
"I feel sick because I feel it is mean because I've done the reality TV thing so I have such strong memories of what it feels like and I just imagine how bad and how nervous they must feel.
"I couldn't be a judge. I would be the worst judge on the history of the show."
