Kristen Stewart before she was Bella! What was she like as an 11-year-old? Click "continue reading" to find out!

Years before her breakout 'Twilight' role, a young Kristen played Jodie Foster's daughter in the acclaimed 2002 thriller 'Panic Room.' Check out our video of the then-11-year-old star talking about her first big Hollywood movie!

"We actually got to know each other really well; the chemistry was really good, so it wasn't hard actually trying to be her daughter," Kristen says of her relationship with Oscar winner Jodie, adding, "It was probably one of the best learning experiences I could ever have."

And of their remarkably similar looks, Kristen says, "It was kind of freaky." Of course, when Jodie was just a couple years older than Kristen's age at the time, she starred in the original 'Freaky Friday' back in 1976!

'Twilight,' in theaters everywhere November 21, finds the now-18-year-old Kristen as Bella Swan, a high school student who risks her life when she falls for a mysterious, good-hearted vampire.
