No longer crazy in love? Beyoncé noticeably changed the lyrics to her song, "Resentment," during last night's performance in Cincinnati, Ohio. Did Jay-Z really cheat on her with Mya?

Bey changed the lyrics "been riding with you for six years" to "been riding with you for TWELVE years," the amount of time the power couple has been together.

Another portion, originally sung "I gotta look at her in her eyes and see she's had half of me," was altered to "I gotta look at her in her eyes and see she's had half of me. She ain't even half of me. That bitch will never be."

The two kicked off their 16-city "On The Run" tour last week at Miami's Sun Life Stadium. The crowd roared as Bey and Jay shared unseen wedding photos and footage of daughter Blue Ivy.

"There were videos of Blue in the pool with her mom, walking holding hands with her parents, Jay Z kissing Blue," a source told Us Weekly. "It was a sweet moment-Jay Z and Beyoncé were both facing the screen watching the Blue videos while they sang 'Halo.' It was like they were singing the song to their baby girl. The two of them were beaming, smiling watching their little girl on the screen."

"It was incredible," they added. "Jay Z said [we're] 'celebrating love tonight' and you could definitely see the love between him and Beyoncé on stage. Their chemistry is amazing."

They have faced bitter split rumors since Bey's sister Solange Knowles attacked Hov in an elevator post-Met Gala. He was allegedly flirting with Kim Kardashian's friend Rachel Roy, and was accused of cheating and financially supporting Mya, who he worked with in 2000 on "The Best of Me."
