The 'Commander' hitmaker – who rose to fame alongside Beyonce when they were members of girl group Destiny's Child – still considers the 'Single Ladies' singer to be a "sister", but she finds comparisons between the pair "unintelligent".
Speaking to The Independent newspaper, she explained: "We're sisters! But claims of negativity and catfights sell way more. People can't think of anything more intelligent than to compare. And that's only natural, I understand.
"That's just the way the industry is, so you find a way to make things your own. But even though my sound sounds like nothing she's done, people are going to find something to say."
In January 2009, the singer parted ways professionally with manager Mathew Knowles – who is also Beyonce's father – however, she insisted the split was amicable on both sides.
She said: "I just needed a change – and he was very supportive, and that's it."
Kelly, 29, recently dismissed rumours of a Destiny's Child reunion, after Mathew claimed it could be on the cards.
She said: "Matthew is not a member of Destiny's child so, with all due respect, that's not a decision he can make - that's up to myself, Beyonce and Michelle (Williams)."
