At the Jules Verne Adventure Film Festival last month during the Heroes event, we noticed that Milo Ventimiglia and Hayden Panettiere were canoodling with each other the whole time, whispering back and forth like giddy schoolkids. But, we chalked it up to nerves and confusion about what was going on during the Q&A. For instance, Milo's answer to "How has Heroes changed your life?" was "I don't really know what to say." Nice. Our tabloid-papparazzo circuit wasn't working properly that day and anyhow, now it's official. The brother/sister set of Peter Petrelli and Claire Bennet are Hollywood's newest incestuous power couple. At least until Sylar swoops in and eats their brains, hoping to gain some of their couple-of-the-moment pheromones.
