Nikki Reed Talks Robot Renesmees On 'Ellen'

The latest round of talk-show musical chairs continues for the cast of "The Twilight Saga: Breaking Dawn - Part 2" as co-stars Nikki Reed and Mackenzie Foy stopped by "The Ellen DeGeneres" show today to chat about the film franchise's finale, due in theaters November 16.

As any Twilighter can attest, Mackenzie's on-screen alter ego, Renesmee, goes through quite the evolution in this conclusion, aging from a newborn baby to a young child in a manner of weeks (thanks, vampire blood!). And for the young starlet playing the adorable half-human, half-vampire wunderkind, it made for some surreal moments on set.

"It's kind of weird because it's not my body," Mackenzie said of the special effects used to paste her face onto different children—and props.

"I was holding the faceless babies, so it was also pretty weird for me," Nikki chimed in. "Her face was not on the baby yet, so that was my job."

A job made even more awkward by where the baby-handlers had to position themselves in order to control the artificial infant.

"They're robot babies," Nikki continued. "There was a man standing between my...between my legs on the floor, looking up at me, moving the robot arms."

Now that sounds truly terrifying.
