Beyoncé's bump

is real, and it's fabulous, and there's an actual baby in there, which she's now revealed is... a girl! Or rather, "an insider" revealed the big news for her, to In Touch magazine.

The "close friend" says "Beyoncé is thrilled she’s having a daughter," and that she had been secretly hoping for a girl. Science has already figured out what the child will look like, and it's believed to be working on its first album in the womb, currently titled, "All The Single Babies."

The kid's going to be living large, with a closet already filling up with Gucci, Vuitton, and OshKosh B'gosh... in her 2,200-square-foot nursery in the couple's TriBeCa apartment.

That's right, a fetus just gave you real estate envy.
