Kelly Clarkson doesn't need a guy to make her feel strong, and on her new track "What Doesn't Kill You (Stronger)," she lets a former flame know it.

The song is the latest tease for her October 24 album, Stronger. Clarkson tweeted the official version of the song after a leak hit the Internet last week. On the dance track, which is all about the power of loving yourself, Clarkson proudly declares over a fist-pumping beat, "What doesn't kill you makes you stronger/ Stand a little taller/ Doesn't mean I'm lonely when I'm alone."

"Stronger" fits in nicely with Clarkson's canon of empowerment-themed, kiss-off tunes. And this time around, she's also moving on to a new guy, singing, "You heard that I was starting over with someone/ They told you I was moving on, over you/ You think I'd come/ I'd come back swinging/ You tried to break me/ But you see what doesn't kill you makes you stronger."

A version of the first song leaked over the summer but the official one had yet to be released until now.

When Clarkson spoke to MTV News about the track, she said it reminded her of one of her own all-time favorites. " 'What Doesn't Kill You,' I can't wait to perform that live," the singer told us. "We've already rehearsed it, and it's so much fun. It's like this big dance anthem. That'll be the one [that's] kinda like 'Since U Been Gone,' [with] people jumping up and down to [it], and it's just kind of really inspiring, so I can't wait to perform that one."
