On Saturday, Sept. 15, the Leonardo DiCaprio Foundation recently celebrated 20 years of advocating forwildlife and environmental protection with a fundraiser in Sonoma, Calif.. But as Chris Martin reminded the crowd before he performed with Coldplay at the bash, Leo’s work isn’t limited to saving animals and the planet. “I studied him very closely for about five or six years,” Chris mused, according to E! News, “and what became clear to me was his unbelievable service, his commitment to the business of cargo shorts.” The joke-prone singer continued: “This is a guy, he’s seen cargo shorts and he said, ‘I’m going to save these shorts from extinction. They should have gone out about 25 years ago. I’m personally going to fund the sort of renaissances of cargo shorts.'” Vulture reports Chris also treated the giggling crowd to a little song about Leo’s penchant for a look that should have died with the ’90s. “Hello, I’m Leo, how do you do? There’s a sad side of me I want to show to you,” Chris sang while playing guitar. “All my movies I’m the star I swear, but they won’t let me wear what I want to wear! You see I have an outfit that I think is fine, so much that I wear it nearly all the time. Find 100 pairs on my wardrobe shelf, so tell the director I’ll be dressing myself: In my cargo shorts, my cargo shorts!” Here’s to you, Leo. Long may your cargo shorts wave.
