Speaking with ET's Kevin Frazier on Monday, Mariah was tight-lipped about the song's true meaning, preferring to leave the lyrics up for discussion.
"I leave that open for the fans to interpret," the 45-year-old pop diva said of her song. "People have to be able to interpret it for their own selves."
"Personally, this song is about loving yourself," Mariah added. "You have to love yourself first… If you don't love yourself, and you're not in a good place with you, than how can you love or do anything else to the fullest?"
The lyrics in question include biting lines such as, "Why you mad/Talkin' 'bout you're mad/Could it be that you just lost the best you've ever had?" And, "Why you tryin' to play like you're so grown?/Everything you own boy you still owe."
"We could take [all my songs] and dissect them and say, 'Who did she write this for?' And, 'What was that about?' But really, there's no way to say who or what was written about," Mariah said. "I also collaborated with different people, so there's all different input and things that happen in the songwriting process. And that's the great thing about writing a song -- you can express yourself, and you can express a little bit of everybody's emotions."
Opening up about what fans should expect from her show, Mariah told ET, "It's Vegas! We had to go really full-throttle."
"I've never done anything like this before, so it's exciting," she added. "Doing all the No. 1 singles, that's something that can attract not only my core fans, but people that just know the No. 1 songs. Some of these songs I've never done live before."
The album and the Vegas show aren't the only things Mariah is focusing on in her life. She's also making sure to spend time with her children
, Monroe and Moroccan -- who she welcomed with Cannon in 2011.
"They're my life," she said of her kids. "They make me happy, and if none of these things were going on, they'd still be everything to me."
So what's next for Mariah? According to her, everything has fallen into place, leading to "an evolution of me."
"This is the beginning of a chapter. A clean slate. So I can't say what's next or what's not next for me. So many things are happening," she said.
As for whether that includes looking for love, the singer played coy.
"I would never look for love, but if it stumbles upon me…" she said, before adding. "Maybe it already has. One never knows."
The legendary singer refused to elaborate.
