The 'Since U Been Gone' hitmaker - who filed for divorce from husband Brandon Blackstock in June after almost seven years of marriage - admitted she is navigating a balancing act between being candid about their breakup, and being fair on their children.

She told 'Entertainment Tonight': "I've been through two divorces in my family, husband as well in his own family as a child. We didn't have social media around when that happened.

"And, like, having kids that run the gambit of four to 19 is a really tough thing. And, you know, I've had conversations with one of our eldest about how difficult it is in the public eye when your parents are so... you know, one of them is so prominent and having to navigate that for them is hard on their hearts.

"I'm just careful also while being real... And I don't think that anything is - like I said - nothing's wrong with anybody, it's just... it happens, and that's why there's nothing to hide about it in that sense. You know, it's just, divorce is a really s***** thing."

Kelly and Brandon have six-year-old daughter River and four-year-old son Remington together, while she is also stepmother to his teenage children Savannah and Seth from his previous marriage.

The 38-year-old star added: "There's a lot of hearts involved here. And you know, that's the thing that's been kind of hard to navigate is I am an open book, but at some point I'm a mama bear more than I am a person in the public eye.

"So, I care one hundred percent more about my children than I do anything else on this planet. So, that's been the hard thing of, like, yes, I'm willing to share my experience and yes, it is the worst.

"I mean, the past few months have been horribly sad. But at the same time, I have to think, 'Hmmm, like, what I say has a domino effect in other people's lives.' "
