Queen B is about to welcome a little princess!

At the Cosmopolitan Awards in London Thursday night, former Destiny's Child member Kelly Rowland accidentally let it slip that her BFF Beyoncé is expecting a baby girl!

Rowland confessed to US Weekly:

    "I think her dad [Jay-Z] is gonna give her everything anyways, all I can give her is love. I think she'll be very well behaved. Her parents will make sure of that."

It had previously been reported that Bey would be welcoming a girl with hubby Jay-Z in February, but the singer has yet to confirm the news.

Hip hop's most royal couple are reportedly building a 2,200 square-foot nursery at their NYC pad for their little one, who will no doubt be lavished with the finest designer baby duds!
