While the pop track is just as infectious as Katy's other singles, it's hard not to think the singer is talking about her soon-to-be ex-husband Russell Brand. In the song, she sings about rising above and beyond a hurtful relationship:
"Now look at me, I'm sparkling / A firework, a dancing flame / You won't ever put me out again, I'm glowing / So you can keep the diamond ring / It don't mean nothing anyway."
'Part of Me' is the first single from her forthcoming album, 'Teenage Dream: The Complete Confection,' due out on March 27. Check out the lyric video for the song below, and grab your copy of the song on iTunes now.
