Olivia wore a calf-length ivory dress complete with netted veil as she filmed the scenes in London.
In real life, Olivia recently divorced Italian prince Tao Ruspoli after eight years together, and is now dating Saturday Night Live cast member Jason Sudeikis.
Chris is happily married to Spanish actress Elsa Pataky and the pair are soon to welcome their first child.
Rush follows James’s rivalry with British racer Niki Lauda and the competition between their Formula 1 racing teams, McLaren and Ferrari.
Set in the Seventies, the story is directed by Ron Howard, and is expected to hit US cinemas in 2013.
