Beyonce throws a 'Party' with Kelly Rowland, sis Solange

Beyonce has released yet another music video, this time featuring the track "Party" from her new album "4." And there are several things we need to say about it.

To those feverish baby-bump skeptics who suspect that Mrs. Jay-Z is embellishing, or altogether faking, her pregnancy: Calm down. The pop star looks svelte in the "Party" video because it -- in all of its trailer-park sultriness -- was shot during the first week of August.

Secondly, let's repeat: trailer-park sultriness. In a glorious mess of fanny packs, headpieces, blender drinks, dice-throwing and dance circles, Beyonce reminds us that even without elaborate choreography, high fashion or cinematic elements she brings one heck of a party.

J. Cole guests, and old friends including B's sister Solange Knowles and former Destiny's Child bandmate Kelly Rowland show up for the festivities, which were shot in an actual trailer park.
