The now-famous tattoo, created by Nikko Hurtado, was applied in three sessions over seven to eight months.
According to the Daily Mail, Sarah isn't that keen, and told The Sun's TV magazine: "Oh God, it's ridiculous. My tattoo has meaning. I don't know what hers means."
The newlywed unveiled the tattoo back in August 2013, and has defended it on social media against critics.
Cheryl also recently explained on the Graham Norton chat show that the tattoo was on her 'bucket list' following a battle with malaria in 2010.
She told Graham: "After I had malaria I created a '****-it list' because life's too short and the tattoo was on the list."
She also revealed the tattoo set her back thousands, adding: "Probably the cost of a small car."
Sarah could be ramping up a bit of competitive spirit as her show Tumble, in which she is a contestant, will go head-to-head for ratings with the X Factor on Saturday night.
According to Contact Music, she also quipped: "X Factor. What X Factor? Who knows if I'll tune in. Let's not talk about ITV. I'm a BBC girl these days."

Whether you like the tush tattoo or not, it's hard to deny that Cheryl pretty much always looks good with her clothes on. See her top looks in our style file gallery below:
