Emma Roberts, Rosario Dawson & Eva Mendes Stunt Coast To Coast (PHOTOS)

It's been a busy week for some of Hollywood's most stylish starlets. The Met Gala got most of the attention, but other things were popping on both coasts, some of which we want to talk about today.

Last night in New York we spotted the Lower East Side's own Rosario Dawson at the Cartier Dinner at the MoMa, one of the few glamorous rooftop parties leading up to summer. Dawson wore a black Dolce & Gabbana dress accessorized with Cartier jewelry and looked flawless.

Meanwhile on the left coast at Nylon magazine's Young Hollywood party another actress was heating up the red carpet: Emma Roberts who was demure in an Elie Saab lace ensemble. Also looking great at that party was singer and now slimmer, Jordin Sparks, who wore a spunky, sleeveless red cocktail dress. Sparks is clearly having fun showing off her new figure.

A few miles away from the Nylon event, Eva Mendes was entering the AMPAS tribute to screen legend Sophia Loren. Mendes, a legend in the making herself, wore a black and green, sleeveless Oscar de la Renta dress.

After the break, see what we saw.
