Crystal Bowersox – “What’s Up” – 4 Non-Blondes – Tonight Show With Jay Leno – VIDEO

UPDATE: Crystal Bowersox tweets confirmation she’ll be singing “What’s Up” on tour, “Just so you know… last nights performance on Leno is a sneak peek at my set on tour this summer… ;)”

Crystal Bowersox performed “What’s Up” by 4 Non Blondes on the Tonight Show With Jay Leno tonight.

She was there, promoting the upcoming American Idols Live Tour, kicking off July 1 in Auburn Hills, MI.

Crystal’s been mum about her tour songs so far, but, I think it’s safe to say she’ll be performing this song on tour.

She looked super at-home with Rickey Minor and the band on stage!  She killed it. Pretty awesome.

Check it out, after the jump…
