A new photography exhibition was unveiled today which shows a raft of stars from the worlds of music, fashion and art supporting the environmental crusade.

The 37-year-old singer and the 18-year-old Game of Thrones actress are supporting the charity by modelling their “Save The Arctic” t-shirts designed by fashion icon and activist Dame Vivienne Westwood, 74.

Keeping her shot light-hearted, Nicole pulled a face and played with her hair.

Towering her highlighted tresses on top of her head, the former Pussycat Doll pulled down the bottom of her graphic t-shirt to make sure the print could be seen.

The photographs, shot by celebrity snapper Andy Gotts, will be displayed in Waterloo Underground station in order to raise awareness for the campaign, which hopes to stop drilling in the polar region by oil giant Shell.

The 60 images, which will be displayed for two weeks, have been strategically placed in the south London station as that is where Shell’s British headquarters are based.

Other stars who are backing Greenpeace include Sadie Frost, Kate Moss, Rita Ora, Naomi Campbell, Aidan Turner, David Tennant and Peter Capaldi.
