Leonardo DiCaprio linked up with his guy friends for lunch at Fred Segal's Mauro's Cafe in LA yesterday. He's home again in California after a Summer getaway with his girlfriend. Leo was shirtless along with a bikini-clad Erin Heatherton for a few days of fun in the Hawaiian sun. The vacation came during a break for Leo from work on Django Unchained with director Quentin Tarantino. Leo didn't join Quentin and his costars Jamie Foxx, Christoph Waltz, and Kerry Washington to chat up Django Unchained at Comic-Con last weekend. Christoph, nonetheless, had only nice things to say about Leo. He said, "I took a liking to [Leo] right away. He's so bright and alert and full of energy and inspiration and imagination."
