So, what how did she respond? The superstar went on a mission to prove they are still a happy couple.
Bey, 33, shared the following photos of her husband, 44, with their daughter Blue Ivy on her website Beyonce.com with the heading 'My Life'. This is clearly her way of shrugging off all that break-up chat.
The internet has gone into frenzy over this cheating story and there's no denying Bey's lyric changes suggest things aren't quite as perfect as she makes out.
The giveaway? She changed the line: "I'll always remember feeling like I was no good / Like I couldn't do it for you like your mistress could" to "I'll always remember feeling like I was no good / Like I couldn't do it for you like that wack b*tch could."
And that's not all. Bey also changed the following line: "Been ridin' with you for six years [...] I gotta look at her in her eyes and see she's had half of me" to "Been ridin' with you for 12 years [...] I gotta look at her in her eyes and see she's had half of me. She ain't even half of me. That b*tch will never be."
So she swapped in a few new lines to give the performance a bit more edge, but does this really mean her and Jay Z are on the rocks?
