Beyonce Bump Video Reveals Her Baby Could Be Born At Christmas

has let slip that her baby might be born in time for Christmas.

The proud singer showed off her bump in a behind-the-scenes You Tube video and inadvertently revealed her new arrival may be due as early as next month.

Stroking her bulging belly, the 30-year-old superstar held up a copy of the New York Daily News from September 23 and declared: "Right now I am actually shooting the video of Countdown, and I am six months pregnant, pretending that my stomach is flat in body suits, hahaha.

"But thank God you can't really tell from the front, but when I turn to the side... Oh baby, oh baby!"

Her baby was originally thought to be due next February, but could arrive in time for Christmas.

In the music video, the star at one point turns to the side in a clinging black dress and shows off her blossoming tummy.

She sings: "I'm tryin' to make us three from that two", before three images of her displaying her bump are shown.

Beyoncé also shows off the sidewards belly rubbing dance move she used at the MTV Video Music Awards in August, when she first announced that she was pregnant.

Beyonce's baby bump has been the subject of much speculation, with some critics even suggesting she wasn't pregnant at all and was wearing a prosthetic.

But the star's best friend, X Factor judge Kelly Rowland, is in no doubt about its authenticity – and earlier this month even let slip what sex the child will be.

"I have no idea what I'm going to buy Beyoncé at the baby shower because Jay is going to buy that little girl every single thing possible," the 30-year-old singer said.

"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!"
