See Future Mom Beyonce Go Bra-less in Joyful "Love on Top" Video

Another week, another instantly iconic Beyonce video.

Now expecting her first child (with husband Jay-Z) the Grammy-winning singer, 30, has released video for "Love on Top," the effervescent single she performed at the MTV Video Music Awards in late August -- when she first confirmed her pregnancy by rubbing her belly.

Beyonce shot the clip either pre-pregnancy or before she was showing. In the video, backed up by five handsome male dancers, she casually croons and struts in a sunny NYC dance studio. As the song progresses, the diva shows off new choreography -- undergoes two additional day-to-night costume changes.

The final look? A sexy tuxedo jacket -- sans shirt or bra.
