Beyoncé’s Destiny's Child bestie, Kelly Rowland, may have inadvertently let the cat out the bag on the gender of B and Jay-Z's upcoming bundle of joy.

“I have no idea what I’m going to buy Beyonce at the baby shower because Jay is going to buy that little girl every single thing possible,” Rowland told Bang Showbiz at the Cosmopolitan <i>Ultimate Women of The Year Awards 2011</i> in London. “She won’t be spoiled, but she will be very well looked-after. I’ll be on hand for babysitting duties and I’m actually very good with messy diapers!”

Just last month, In Touch Weekly announced the power couple were having a girl, but, the statement wasn't confirmed by neither of the camps involved.—Mark Lelinwalla
