Beyonce changed a lyric while she was singing "Resentment" the other night in Cincinnati. One word, actually . . . but it was enough to convince people that Jay Z CHEATED on her. (The original line is "Been ridin' with you for six years," and Beyonce changed it to "Been ridin' with you for 12 years," which is the amount of time she's been with Jay Z. And the rest of the song is about a cheating lover.
