12. ERIN DEAN

Show: The Journey of Allen Strange
As 16 year-old Robbie Stevenson, Erin Dean was our kind of girl - smart, compassionate and unshamed to say she's shacking up with an alien. Since the groundbreaking SNICK show, Dean guest starred on other teen series, including Boy Meets World and Figure It Out, but she is now retired with no plans to ever act again.
