Alicia "Al" Lambert is a main character on ABC family comedy Step by Step. She is portrayed by Christine Lakin.
Al is Frank's only daughter, who is depicted as a tomboyish all-American girl, quite akin to her brother JT and father Frank. She is typically addressed by her nickname, the more masculine name "Al", and is rarely referred to as "Alicia". Several episodes during the seventh and final season centered on her newfound interest in acting. She is openly hostile towards Dana, Karen and Mark, which is often a point of contention with Carol, as well as Frank, who is demanding his own children be more accepting of their new family.
