Following dinner with her gal pal, Michelle flew to Washington DC as part of the Creative Coalition's Arts Day on the Hill.

She wrote on Instagram on Thursday: 'Proud to be a part of #TheCreativeCoalition's 2015 Arts Day on the Hill! We must bring funding back to the arts!

'Every child deserves to have a creative outlet.#MakeADifference #creativeDC'

It is an effort by the non-profit organization, the Creative Coalition, to convey to national leaders the importance of championing the arts.

Kate is currently anticipating the release of her new film, The Face Of An Angel, co-starring Cara Delevingne and Daniel Brühl, on June 19, 2015.

In the Michael Winterbottom directed drama, both a journalist and a documentary filmmaker chase the story of a murder and its prime suspect.

Kate portrays a journalist, and in an interview with The Guardian, marvelled at the parallels between being an actress and a reporter. 

'Say you're having a terrible argument with your boyfriend and you're breaking up. 

'For an actor there's this still slight distance where you're observing the event, thinking: "This is what it looks and feels like to be breaking up with someone."

'I think that journalists have that same ability to step back and see things from a different perspective.'
