No, no, no: Not Adam Lambert. Remember Alex Lambert, the 19-year-old rocker who wowed the judges on the last season of American Idol, only to be shockingly cut before making it to the Top 12?

Well, he didn't let that stop him from rushing right into the next big opportunity. Two weeks later, he moved into the 19 Entertainment-run "If I Can Dream" L.A. house, joining five young hopefuls already pursuing their own path to fame.

And now it's all falling right into place, isn't it? Lambert's debut music video, "I Didn’t Know," will premiere on this Monday, July 26, as he plays a few pianos across all five boroughs of NYC as part of Sing for Hope's Play Me, I'm Yours public art project.

But readers (that's you!) can get an advance look at Lambert's new vid, courtesy of Clear Channel and iheartradio. Also check him out jamming with Lee DeWyze and other Season 9 Idols and singing the National Anthem!
