Kate and Chloe previously worked with director Stillman on the 1998 comedy, The Last Days of Disco.

In an interview with the Today show, Kate discussed their reunion since their first movie, which was an era of 'pre-cell phones and internet,' which only allowed the cast to run into each other on occasion.

'We were suddenly plunged back down into working together. What was funny was that everybody's had so much life and stuff happen to them, and it was kind of very similar vibe. Everybody's a little bit of an oddball and it all kind of worked,' she said.

Kate, who is said to have split from director husband Len Wiseman, was in a relationship with Michael from 1995 until 2003, although they never married.
