Beyonce already picking her baby's name

The star's sister lets slip that Bey and Jay-Z already know the sex of their unborn child

It must have been all the excitment surrounding the pregnancy, but Beyoncé's sister, DJ Solange Knowles, revealed that her sibling and husband Jay already know the sex of their first baby.

"I certainly didn't find out (about Bey's pregnancy) the way you guys did" said Solange to the Wall Street Journal during New York Fashion Week, adding that she'd known about the arrival of a nephew or niece for quite some time before it was publicly announced.

Bey's little sister also said that the ""Best Thing I Never Had" singer and her rapper husband have already started picking names for the new arrival.
