Beyonce walked the black carpet, debuting her baby bump for the very first time, and from the looks of it - she's a few months along!   The 1+1 singer arrived to the VMA pre-show in a flowy, red dress, happily holding her stomach to reveal her bump.

Knowles has a big night ahead of her, as she has been confirmed as a performer during the popular awards show.  She has already won an early award for Best Choreography for her video Run The World (Girls) and is also nominated for Best Female Video and Best Cinematography.  Hopefully all the pressure of tonight's show doesn't stress out the brand new mommy-to-be too much!

What do you think of Beyonce's announcement!? Is it about time, or did you not see this coming!?
