Violet Affleck was very surprised to learn Jennifer Garner lived at her house. The four-year-old offspring of Ben Affleck and the Alias star stormed home from school one day after a classmate told her she lived with Jennifer Garner.

"Mom, who is Jennifer Garner and why are people saying she lives with us?" Jen's friend, Jessica Biel, shared with Marie Claire for the March issue. "She just knows me as Mom, so I did have to explain to her for the first time about the difference," Jen says.

She's also been "holding down the fort" while husband Ben Affleck writes, directs and stars in Boston crime drama The Town. To hear Jen tell it, Ben is working at Ryan Seacrest-level intensity.
