But was he serious?! After being plagued by a ton of divorce rumors, this is the last thing we expected! Then again, Beyonce's estranged father Matthew did recently suggest that his daughter played up a possible split just to promote the tour...

Jay Z and Beyonce performed their final On The Run show in Paris on Saturday night, and when taking the stage for "Beach Is Better," Jay seemingly switched the lyrics at the end from "'Cause I replace it with another one" to "Cause she pregnant with another one."

The video above is from last night's show, and while we can't tell whether Jay actually said the word "pregnant," a source tells Radar, "For the last month, Jay has been fiercely protective of her, just like when she was expecting Blue Ivy. He’s been doing everything he can to ensure that Bey is in a stress-free bubble." Time will tell!

Beyonce, 33, and Jay Z, 44, first became an item in 2002 and got married in 2008. In January of 2012 the couple welcomed daughter Blue Ivy.
