has released a new trailer in which Kirsten Dunst, Isla Fisher and Lizzy Caplan set about throwing a pre-marriage party for newly engaged pal Rebel Wilson.

Directed by Leslye Headland and co-starring James Marsden and Adam Scott, Bachelorette opens in the US on 7 September 2012, with a UK release date to be confirmed.
