Hayden Panettiere was at The Grove Wednesday to promote her upcoming Scream 4 movie on the Mario Lopez hosted Extra. Hayden said she was a shoe-in for the movie because her fireman father made sure she learned how to scream bloody-hell from a very young age so that she could scare off potential attackers.

The former Heroes star said, “I’m a fireman’s daughter. He used to tell me all the time when I went to the mall with my friends, ‘What do you do if somebody comes up and grabs you?’ He taught me to scream, ‘You’re not my daddy, you’re not my daddy’. So I had a lot of practice screaming, ‘You’re not my daddy.'”

On a somewhat similar note, the 5’1″ Hayden made headlines earlier this week when she told Ellen DeGeneres that the most embarrassing or rudest question people ask her most often is how she gets it on with her 6’6″ boyfriend, Ukrainian heavyweight boxer Wladimir Klitschko.

“I get the rudest people coming up to me and they’re like, ‘does it work?’ ” she admitted to Ellen. “Yeah, it works. We find a way.”

Ellen said “I know what you’re talking about, but I’m in shock.”

Hayden responded, “Where there is a will, there is a way!”

Ellen expressed her disbelief that random people would ask such intimate questions. Hayden said, “They do. And they are very conservative people most of the time but they just have to know. ‘Like, I have to know, I just have to ask you this question. I’m really sorry but…’ ”

Hayden added, “I don’t mind it. I find it amusing.”

“Really?” Asked Ellen. “Then how does it work?” she joked.

Oh Ellen!
