Hayden Panettiere Joins 'Extra' at The Grove

"Scream 4" star Hayden Panettiere stopped by The Grove to chat with Mario Lopez. The petite star would not reveal whether her character dies in the movie, even though Mario tried to trick her into telling him. "So, how do you die?" Lopez asked. Hayden replied, "You don't know that I die..."

Panettiere also talked about hanging with her heavyweight champion boyfriend, Wladimir Klitschko, who happens to tower over her at 6'6"! She joked about their height difference and said, "We were at the pool once and he was looking to find me and I'm standing next to him and I'm like, 'Dude!' -- and he walks away so I grab his arm and I'm like, 'Babe, it's me! Turn around!'"
