She has Ashkenazi Jewish ancestry on her father’s side and is of English, German, and Irish descent on her mother’s side.
Hated the Catholic school girl uniform she had to wear during the fifth season of That '70s Show (1998).
Due to the seven inch height difference between her and co-star Mila Kunis on That '70s Show (1998), Laura and Mila were often filmed sitting down so that they could appear in the frame together. At other times, Mila wore platform shoes to give herself four extra inches.
Is proud of being a New Jersey native.
Said her favorite actor is probably Harrison Ford.
Laura appeared in the 2001 American independent film Southlander for her role as Seven Equals Five.
