Did Beyonce hint at problems in marriage to Jay Z during live show?

Beyonce changed the lyrics in her track 'Resentment' whilst performing the track at the Ohio stop of the On The Run tour at the weekend - referencing her marriage in the new version of the break-up song.

Whilst performing the track, which featured on Bey's 2006 album B'Day, the singer changed the lyrics from "Been ridin' with you for six years" to "Been ridin' with you for twelve years" - which is how long she's been with Jay-Z.

That would all be well and good except for the fact that 'Resentment' is a powerful song told from the point of someone who's been cheated on. Other lyrics include: "Look what you've done-done to me now, I gotta look at her in her eyes and see she's had half of me, she ain't even half of me."
