Kelly, you got a lot of 'splainin to do!

While attending the Cosmopolitan Awards in London Thursday night, Kelly Rowland slipped and revealed the gender of Beyonce's upcoming bundle of joy.

When asked what she might get the baby at the baby shower, Rowland told Us Weekly, "I don't know. I think her dad [Jay-Z] is gonna give her everything anyways, all I can give her is love."
