Stepping out on the eve of the premiere of their latest work, stars of “The Great Gatsby” were on hand for the Catherine Martin and Miuccia Prada Dress Gatsby Opening cocktail party on Tuesday (April 30) in New York City.

Decked out in a retro pale pink Prada frock, Isla Fisher happily posed on the arrivals carpet as did her handsomely dressed co-star Tobey Maguire, who came with his wife Jennifer Meyer.

Joining celebs from Hollywood and Washington, Katy Perry headed to the White House Correspondents' Association Dinner at the Washington Hilton on Saturday (April 27).

The "Wide Awake" singer donned a strapless emerald Giambattista Valli gown with twig embellishment at the waist and her long dark hair worn to the side.

It's been almost a year since she was declared a single lady, and Katy Perry finally addressed the questions about her short lived marriage with actor Russell Brand.

While spending time at the ASCAP "I Create Music" Expo in Hollywood last week, the "Part of Me" songstress decided that it was time to open up about the divorce.
