You know Hayden Panettiere loves singing along to that Lindsay classic! We spotted the Heroes actress at a red carpet event in Beverly Hills last night where the barely-legal hottie put to rest romance rumors between her and co-star Milo Ventimiglia. When asked if she was dating the 30-year-old, she quickly responded with: "No, it's just a rumor." Well, there you have it! Hayden says it's not true... at least for now, that is!
