Lukas Haas and Leonardo DiCaprio are kinda attached at the hip these days. The twosome just got back from a beach vacation with Bar and here they are together doing some male bonding in LA this weekend. Leo has his life-long buddies and Lukas is one of those guys who seems to be a permanent fixture in his life. The boys cruised around on their mopeds and then grabbed some lunch together. Leo looks a little goofy in his oversized helmet, but we're happy he is being safe and protecting that pretty head of his — you can never be too cautious on those bikes.
