They may rely on each other when it comes to saving the world on TV, but the bond between Heroes' Milo Ventimiglia and Hayden Panettiere is apparently strictly platonic in real life. According to fellow cast member James Kyson Lee, there's no truth to the rumor that Milo and Hayden are dating. "It is not true," Lee said at the Lift Up America charity event in Hollywood on Sept. 25. "It's a rumor and I don't know why people are jumping all over that. Milo will be the first one to tell you that they're 12 years apart. So it's not true."

Lee participated in Lift Up America's "Giving Hope Tour," where 1,400 underprivileged kids from all over Los Angeles walked down the red carpet as celebrities cheered them on, and was more than happy to share the limelight. "Today the kids are the stars," Lee said. "We want to tell them to celebrate life and to go for everything that they believe in and dream of. We want to encourage them. We want to give them the opportunity and just feel like they are the center of attention." - Reporting by Carita Rizzo
