Rusting old petrol pumps outside a long-closed rural village petrol station are seen on a minor road near Trowbridge, Britain, October 21, 2016. From art deco apartments in Sussex to a trendy burger bar in London, some of England's former petrol stations are enjoying a new lease of life following creative makeovers. The overhaul opportunities have been created as more than 20,000 stations closed in the United Kingdom over the past 40 years, according to the U.K.'s Petroleum Industry Association (PIC).

The photo project was done for the organization Fishlove and included some other U.K.-based celebrities posing in the buff with critters ranging from bass fish to sharks. Its goal is to raise awareness of how overfishing is destroying the oceans. The release of Gillian's nearly nude pic, which was snapped by French portrait photographer Denis Rouvre, is timed with a European Parliament vote on banning destructive forms of deep-sea fishing in the Northeast Atlantic. The Fishlove organization is trying to rally voters to sign a petition ending deep-sea trawling – which, according to scientists, is negatively impacting the fish population and their habits – and Gillian solicited signatures in a Twitter post.
