It is the fashion industry's night of nights, and as two of the fiercest celebrities around, Rihanna and Beyonce were always going to give the models and designers a run for the money.
Beyonce, who has dropped a few dress sizes in recent months, decided to show off her newly svelte figure in an extremely tight gown by Emilio Pucci last night at the Costume Institute Gala in New York.
And while, other than a cut-out of her décolletage, the 29-year-old singer remained covered up in her breathtaking gown, Rihanna turned heads in a daring Stella McCartney dress that left little to the imagination.

Beyonce was joined by her husband Jay-Z and showed off her figure in a form-fitting black fishtail gown with exquisite gold embroidery.
The stunning dress had a high neck design, complete with a cut out oval panel which revealed her décolletage.
Of course, having her husband by her side proved helpful because the tight-fitting nature of the ensemble meant it the Single Ladies singer needed assistance climbing the stairs.
