Leonardo DiCaprio met up with a group of guys, including his best friend Lukas Haas, for a sunny afternoon in LA yesterday. Leo's casual outing came after a dressed-up weekend that took him to the GLAAD Media Awards, where he donated $61,000 to the organization. He continued the celebrations on Monday, when he marked Earth Day with a tweet urging his followers to check out a bunch of "great slideshows on oceans, water, food & energy, it's all connected." Leo will continue to be in the spotlight in the coming weeks since he'll be handling press for The Great Gatsby ahead of its May 10 release. Get ready for the movie to hit theaters with a look at all the reasons we're excited to see The Great Gatsby!
