The 23-year-old actress, who shot to global fame post 'Twilight', is currently going through a rough period after it was revealed that she had an affair with the married director Rupert Sanders.

The actress has issued a public apology to boyfriend Robert Pattinson since then even as Sanders struggles to save his marriage with wife Liberty Ross. It is being claimed that Amber Heard will join the cast of 'Cali' after Stewart's departure.

It seems the actress is not ready to face awkward questions from the media or angry Twihards at the London red carpet for 'On The Road'.
