Kelly Rowland accidentally mentioned the sex of her baby-to-be during an interview with FOX411. The singer, who's expecting her first child with her husband and manager Tim Witherspoon, spilled the beans while promoting Caress, the skin-care line for which she's a spokeswoman.

"We're very excited," the 33-year-old singer said, "so far, everything has been good. I just feel like the baby is already [spoiled] rotten- like literally, my Caress family has gotten him all of his little bathing stuff, his toys. It's just so cool."

Realizing that she had mentioned a very specific pronoun, Kelly sighed heavily and laughed, "It, it's... aw, f**k it! It's a boy. It's a boy!"

Kelly then told her publicist to place an emergency call to her husband. She asked, "Can you please tell him that I spilled the beans?" She caressed her baby bump and said, "I'm sorry, baby. But yes, it's very exciting."

Kelly also revealed that her baby might have a talent for music since he responded with movement each time they played him music. "When you play music, period," she explained, "but really to hip-hop right now!"

However, the expecting singer doesn't plan on molding him into a future hip-hop crooner. She said, "I'm not going to put any expectation on him. He's his own human being. I'm just happy to be a part of the process."

Kelly first hinted at the sex of her baby-to-be last month when she announced that she was expecting. She posted an Instagram picture of a pair of baby Jordan sneakers next to a larger pair. She captioned the picture with, "I'll be stuntin like my daddy."
