Chris Martin was quick to point out that environmental work isn’t DiCaprio’s only area of expertise after taking the stage for Coldplay’s performance at the Leonardo DiCaprio Foundation’s 20th anniversary gala in Northern California on Saturday. “I studied him very closely for about five or six years and what became clear to me was his unbelievable service, his commitment to the business of cargo shorts,” Martin quipped before performing an original song about the controversial menswear item.
