Katie Holmes & 'Romantics' Costars Party In J. Crew's Fall Line

Etertainment Tonight

"I like to shimmy," actress Katie Holmes jokes with Josh Duhamel. 'The Romantics' cast share some dances and some laughs as the cast models the new Fall J. Crew Collection -- and ET has the behind-the-scenes moments from the photo shoot…

With a DJ on the sidelines and cupcakes in hand, Holmes, Duhamel, Malin Åkerman, Adam Brody, Jeremy Strong and Rebecca Lawrence celebrate in the newest party attire from J. Crew. "We don't really go anywhere without a DJ," Duhamel jokes. "Whenever I'm near Katie, I know there's going to be delicious cupcakes somewhere."

Holmes loves her J. Crew party dress, telling cameras, "At night, if I venture out, I'm going to belt it, heel it and go for it."

Åkerman adds, "I actually didn't expect the glitter from J. Crew and I really like it."

"We have been fans of J. Crew. … It feels very much like 'The Romantics,'" Holmes exclaims.

In the film, Holmes, Duhamel and "True Blood" actress Anna Paquin play former college friends caught in a love triangle over the course of a wedding weekend. 'The Romantics' hits theaters September 24.
