"American Idol" honcho Nigel Lythgoe has balls -- he's asking Prez Obama to come on the show to do the song that made him even more famous -- with Al Green.
Seems Nigel was blown away by Obama's short rendition of "Let's Stay Together" at the Apollo Theater earlier this month.
So Nigel just tweeted the Prez, "We loved your vocal performance so much we'd love to invite you on to American Idol this Season for a duet with Al Green."
We'd watch. But is it a good move for the Prez?
