Did Jay Z announce Beyonce's 2nd pregnancy at Paris concert?

Jay Z may have subtly announced that he and his superstar wife Beyonce are expecting their second child. While performing his new song 'Beach is Better' at the Paris leg of their On The Run tour, Jay Z changed up the lyrics to make the announcement.

The original lyrics is; "Can't take this money with you, Burn this shit up like I'm richer, Nigga's asking, If the oven's on'

Instead he spit; "Can't take this money with you, Burn this shit up like I'm richer, Nigga's asking ...cause she pregnant with another one"
