A source close to pregnant pop star Beyonce has spilled the beans on baby Jayonce's gender! Following previously reported speculation, the source has confirmed that Bey and hubby Jay-Z are expecting a baby girl!

Beyonce's mom Tina Knowles revealed that she and those close to her famous daughter already knew the baby's gender, and it looks like the singer's friends just couldn't keep the secret to themselves. The insider reportedly told In Touch, "Beyonce is thrilled she's having a daughter."

And while the mom-to-be would've been happy with a healthy child of either sex, she reportedly was secretly hoping for a girl. "She and her mother are so close, and she's wanted to have that relationship with her own child," the source revealed.

The source also alleges that the fashionista is so eager to play dress-up with her baby girl that she has been swiping her credit card to buy the future diva mini outfits from designer brands like Gucci and Louis Vuitton. "Her family's afraid there won't be anything left to buy for her baby shower in December!" the source claimed.

To go along with her wardrobe fit for a princess, Queen B's daughter will have a palace-sized nursery to match -- a reported 2,000 square foot nursery to be exact. We're guessing it will be pimped out with a gilded crib and diamond-encrusted baby monitor, too.
