(Cover) - EN Showbiz - Kristen Stewart could strongly "relate to the maternal aspect" in the latest Twilight instalment.

The actress, whose character Bella Swan falls pregnant with her vampire husband's baby in Breaking Dawn, doesn't think she is too young to understand motherhood.

At 21, Kristen may not have the desire to have children herself yet, but the brunette beauty doesn't consider it unlikely for someone her age to become a mother.

"I don't think it's far-fetched for someone my age to be having a child," she told British magazine Closer. "One of my best friends just had a baby and she's very, very young. I definitely related to the maternal aspect of things very strongly."

Kristen, who is dating Twilight co-star Robert Pattinson, seems unlikely to be planning a pregnancy herself yet.

The notoriously private couple, who have been dating for around two years, do not permanently live together and have to work around their busy schedules to spend quality time together.

Instead, they share the care of Robert's dog Bear, while Kristen also owns three canines, two of which are hybrid wolves. (C) Cover Media
