The 35-year-old, who is currently filming John Martin MacDonagh's film Calvary alongside Brendan Gleeson, has been on set in Rush for the past few weeks.
But she swapped Rush for the red carpet in Los Angeles.
The red-headed star was in LA to accept a Hollywood Spotlight Award for her role in Robert Zemeckis' new drama Flight.
And she mingled with other recipients, including Ben Affleck, Robert De Niro, Bradley Cooper and Nicole Richie.

Kelly stars alongside Denzel Washington in Flight, due to hit our cinema screens soon.
