If you watched the season finale of American Idol last night, you likely watched Mariah Carey put on a show that now has the Twitter world going crazy with accusations.

Mariah Carey was spot-on during her live performance singing “Hero,” “Make it Happen,” “Vision of Love” and “We Belong Together.” The problem? She was too spot-on to some viewers and her flawless performance has some wondering if she faked it.

Mariah Carey, if you are going to lip sync on American Idol, at least attempt to make it look real. Or don't perform on behalf of America.—

Just saw @MariahCarey lip sync from last night @AmericanIdol and @jimmyfallon could have done a better job with those songs.—

Disappointed in @MariahCarey and her lip syncing on the show and as a JUDGE! More disappointed that the @AmericanIdol show allowed it!—
