Woo! Sing it Stevie! Ha!
Last night, Stevie Wonder made a surprise appearance on American Idol to sing a Motown classic with the show's Top 11 contestants.
But after his performance was signed and sealed, he delivered a surprise for Idol judge Steven Tyler - a birthday song!
Check out the video (above) to see Stevie sing Happy Birthday to Steven live!
Such a nice gesture! We bet he really appreciated it!
