Kelly Rowland has confirmed she is expecting a baby boy

Asked about her pregnancy, the 'Dilemma' hitmaker told FOX411: "We're very excited. 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."

The former Destiny's Child immediately realised her blunder and said: "It, it's...aw, f**k it! It's a boy. It's a boy!"

She then asked her publicist to contact her husband, saying: "Can you please tell him that I spilled the beans?"

It seems the singer was desperate to keep the news a secret, as she also told her bump: "I'm sorry, baby."

Kelly first sparked rumors she's expecting a boy when she was spotted browsing for blue baby clothes at children's supply store Juvenile Shop in Sherman Oaks, California, earlier this month.

An eye-witness at the time revealed that Kelly was cooing over the tiny clothing and reportedly said: "Oh my god, this is so little ... this is so cute!"

The 'Motivation' hitmaker previously praised Tim for being "super supportive" during her pregnancy.

She said: "He's so hands on and I'm just so blessed.

"I just love him, he's like the greatest guy ever. He's so awesome I just can't believe how blessed I am...and he is too! He's an amazing man."
