"Hayden Panettiere lost her cool at an event in Hawaii over the weekend.
The 19-year-old Heroes star -- who recently split with Milo Ventimiglia because of her club-going ways -- was testy when she first stepped on the red carpet at a fundraiser benefiting the Rehabilitation Hospital of the Pacific Foundation Sunday in Honolulu.
"Back up!" she yelled at photographers.
After posing for photos, she brushed by reporters.
A female television reporter touched her shoulder and asked, "May we talk with you, Hayden?"
Miffed, the actress jerked her head around and screamed, "Don't you ever touch me!"
She then icily asked a red carpet handler, "Oh, am I supposed to do interviews?"
Approaching various media outlets, she snapped again: "You all make my life miserable" and refused to answer any questions.
After the red carpet, Panettiere hung out in a private cabana with Justin Long and his brother. She then moved to a private dining room, where she and Long sat across from one another, chatting for more than an hour."
I guees being in Hawaii will do that to anyone...
