Her Character: Renesmee is far and away the most important new character to be introduced in Twilight: Breaking Dawn -- Part 2. Not only does the half-human/half-vampire daughter of Bella (Kristen Stewart) and Edward (Robert Pattinson) become the major focal point of the plot, she also ends up becoming the love interest for Jacob Black (Taylor Lautner).
Who She Is: Young model Mackenzie Foy landed the role of a lifetime when she was cast as Renesmee in Breaking Dawn. The 11-year-old has acted in commercials and had guest appearances in shows like FlashForward and Hawaii 5-0. "She's a great actress. She's really sweet," Robert Pattinson told MTV News about his young costar.
