The 'Elephant' singer told the Huffington Post UK that she does not want to make her love life public knowledge.
"When you are in a relationship outside of the spotlight it's hard enough to keep the spark going, but trying to do that in the media glare can be quite challenging," Burke said. "I dread the question in every interview I do when they ask me about my relationships.
She continued: "Sometimes I don't really want to talk about those things, that's a part of my life I like to keep to myself."
However, the 23-year-old admitted that her mother Melissa Bell - who shared her thoughts on Whitney Houston's death for Digital Spy earlier this week - used to advise her to "remain single for your male fans".
"But I disagree with that - I don't think that has any sway on my fans, I don't think they would be that affected by it," the X Factor winner said. "For some artists however it can play a part. From a male point of view it can be different I think, as sometimes the female fans can be a bit more tricky, and feel like they have more of a hold over the artists.
"I think that just shows how dedicated fans can be though - fans do really make the whole music cycle keep turning, they are the crux of everything and I am so thankful to my loyal fans who have been there supporting me from day one."
Burke concluded: "So, for me the whole relationship thing is just something that I'm putting on the backburner and something that will come later. I'm having far too much fun at the moment and doing the job of my dreams so a girl really can't complain."
