Watch: Katy Perry (Wide Awake) Lyric Video

Katy Perry knows what she's doing, that's for sure. On the heels of releasing her single "Part of Me" at the Grammy Awards, the "California Gurl" singer released "Wide Awake" at last night's 2012 Billboard Awards.

If you're thinking the song sounds a little like a big ol' adios to her ex-husband Russell Brand, then you may be right! The lyrics are: "I wish I knew then what I know now/Wouldn't dive in, wouldn't bow down/Gravity hurts/You made it so sweet 'til I woke up on the concrete." Ouch!

According to Celebuzz, during a recent interview Katy talked about her personal songs and getting her feelings out there instead of keeping them bottled up inside. “Well, there were two songs that I had from "Teenage Dream" that I couldn’t put on, it was ‘Part of Me’ and ‘Dressing Up.’ And then I knew we were doing the re-release and so I was like, ‘I got to get in the studio,’ because I can’t wait eight months to be able to put out this feeling that I’m feeling right now, ’cause God knows it would take eight months to do another record. I couldn’t do it on the fly, to set up records it takes time.”
