Beyonce's uber-tight fishtail frock makes other stars green with envy

Beyonce Knowles looked stunning in a shimmering green fishtail number at a glitzy Hollywood bash, although it was clearly hard to breathe in its constricting grasp.

The bootilicious singer looked positively fit to burst out of her designer frock, which hugged her extremely curvaceous figure.

But even she had to concede to practicality, as she changed into a less restricting yellow number when she took to the stage to perform.

The 25-year-old diva worked the red carpet at the Movies Rock event, a TV special that will pay tribute to some of music's most iconic moments in film.

Also at the show, which was at the Kodak Theatre, was Jennifer Lopez, who revelled in showing off her baby bump.
