Barack Obama may have accidentally revealed the sex of Jay Z and Beyonce's twins.
The former US President gave a speech about Jay Z, as he became the first rapper to be inducted into the Songwriters Hall of Fame.
Addressing the crowd, he said:
"Jay and I are also fools for our daughters, although he's going to have me beat when those two twins show up."
He added: "And let's face it, we both have wives who are significantly more popular than we are."
