Hayden Panettiere once saved her HEROES co-star Masi Oka's blushes after he was nearly caught out sporting a lovebite on his neck. Oka hailed the 18-year-old actress a hero after her experience with the world's media prevented him from an embarrassing situation. He tells People.com, "I remember one day we went to this premiere and I didn't realise it was a press event and they were taking pictures and Hayden came up to me and said 'Masi, you have a hickey! We have to cover you up!' And I was like, 'Whoa. I didn't know that.' "Hayden always takes care of all of us."
