Usher and Will.I.AM take “OMG” to American Idol

Raymond VS. Raymond, is in stores now and Usher is doing his darn-dest to assure that it will be access. The R&B heartthrob stop by the obligatory American Idol and bought along some help in the form of Black Eyed Peas, front man Will.I.AM.

The two performed Usher’s new tune “OMG”

Side note: Usher in on pace to sell almost 400k next week and doesn’t even have a hit single. That’s what I call a fan-base!

Was is me or were Usher’s vocals…off? Not to mention the number was really flat in the beginning. Towards the end when Usher “Sasha Fierce” began to come out….is when the number finally actually gained some steam.
