Allison was on many of the episodes of "Drake & Josh" on Nickelodeon. She was always out doing Josh in scholastic competitions and later became Josh's girlfriend. She was a cutie back then also. Oh, she was also in a Disney movie with Kay and Danielle Panabaker. I think the title is "Read 'Em And Weep".
