Grenier is best known for playing Vincent Chase on HBO’s “Entourage" as well as for his work promoting environmental conservation.

On "Entourage," the fictional movie star Grenier played was offered the role of Aquaman in a fictional superhero movie. Blackburn's reference to the plot line could mark her as a fan of the long-running HBO series, which concluded last year, or perhaps just of Grenier's work filming advertisements for nonprofit conservation group Oceana.
