Justin Bieber, who is 17 but has the physique and sunken chest of a sickly 10-year-old, is in Hawaii today with Selena Gomez, and yesterday they went to the beach and held hands. It was pretty neato, or however those nerds would describe it. It's like a fan-fiction story come to life. Today they'll probably find an old treasure map and get chased by a guy in a grass skirt and scary mask. And this once quiet vacation will turn into... the adventure of their lives!
