Announcing milestones on stage is their thing! Jay Z sparked brand new buzz that Beyonce is pregnant with their second child when he changed lyrics to a song during the couple's last On The Run show in Paris on Friday, Sept. 12.

The rapper, 44, made the possible announcement while performing his hit song "Beach Is Better," rapping, "Cause she pregnant with another one."

The tantalizing clue flips the conversation about the couple, who have endured serious marriage trouble over the past several months — with divorce even a possibility — multiple sources have told Us. They somewhat quelled fears when they shared a kiss on stage after Beyonce's Michael Jackson Vanguard Video Award performance at the MTV Video Music Awards late last month and packed on the PDA at the 2014 Made In America Festival over Labor Day weekend.

Beyonce, 33, and Jay Z tied the knot in April 2008 and welcomed daughter Blue Ivy in January 2012. Like her husband's supposed admission, the singer too revealed they were expecting a child on stage when she rubbed her baby bump after singing "Love On Top" at the 2011 VMAs.
