Barack Obama On 'American Idol'? Nigel Lythgoe Invites The President, Al Green To Show

From the American President to American Idol?

Barack Obama's rendition of Al Green's classic "Let's Stay Together" at an event in Harlem earned him a ticket to Hollywood (if he wants it), as "American Idol" producer Nigel Lythgoe took to Twitter early Tuesday to invite the president to sing on the reality show.

"@BarackObama we loved your vocal performance so much we'd love to invite you on to #AmericanIdol this Season for a duet with Al Green," Lythgoe wrote.

It's a shrewd business move; "Idol" ratings are down significantly this year, and rival singing competition "The X-Factor" stole all the headlines on Monday night by parting ways with host Steve Jones and judges Paula Abdul and Nicole Scherzinger.

Obama's vocal work has already helped spur record sales, as in the few days after his singing lit up YouTube, digital download sales of Green's song were up 490%.

Lythgoe also passed judgment on the vocal stylings of Obama's leading presidential rival. Mitt Romney sang "America the Beautiful" at a Florida rally on Monday night, earning negative reviews after the video hit the airwaves and web. Lythgoe was among the tough critics.

"If it were an election based on vocal talent @barackobama would beat Romney hands down. Mitt was very flat singing 'America the Beautiful,'" he tweeted.
