Meanwhile, Kate has been busy promoting her new film Steve Jobs, with the highly anticipated film delving into the dark side of the iconic Apple founder, in which she plays Mac developer Joanna Hoffman.

Written by The Social Network and The West Wing's Aaron Sorkin, the film goes behind the scenes of three iconic Apple product launches, and ends in 1998 with the unveiling of the iMac.

It will be released on October 23 in the US and on November 13 in the UK.
