her destiny?...

Katharine McPhee's "original" song/soon-to-be single is a tune entitled My Destiny, written by Hanne Sorvaag, a Norwegian singer/songwriter.

If you scroll down her biography, she does have a link to her most recent album. (I personally, like the song Love Sucks, like anyone who would write/sing a song by that title, and think that should be the coronation single. But that's just me.)

So no Tamyra for Katharine. That's gotta be good news.
