Va.

But Leah, 19, won't let the lady thugs get away with it. An insider tells OK!, "We know who they are." Another source says, "Leah is going after them. She wants justice and she'll stop at nothing to make sure it's done."

A source says it started when Leah was exiting the theater with Jeremy and an older woman began following her and calling her names. The 40-something assailant became agitated when Leah opened her car door.
