Demi Moore, Kate Hudson, Anne Hathaway Hook Up In New York

Demi Moore, Kate Hudson and Anne Hathaway hooked up at a star-studded bash in New York last night (April 30).

The stunning acting trio all sported dark and mysterious dresses for the Cartier 100th Anniversary event.

In keeping with the bash, Kate finished off her look with a super-expensive Cartier sapphire platinum necklace.

Eva Mendes and Jessica Biel – who was joined by boyfriend Justin Timberlake – also shone out the red carpet.

Kate and Demi – who has spent the last few weeks voicing support for Britain's Got Talent's Susan Boyle – later headed off to the after-party together.

Perhaps Demi wanted to talk more about fabulous Susan?
