A new zip code for Jessica Lucas.

Jessica Lucas is going from one Los Angeles-set CW school to another. The actress, who played "21 Jump Street"-style undercover cop Kim at West Beverly on "90210," has been cast as "Melrose Place"'s idealistic inner-city teacher, Riley Richmond.

According to the Hollywood Reporter, the Riley character is beautiful, wealthy, and engaged -- to Michael Rady's Jonah. She's having second thoughts about the wedding though, which prompts us to wonder if she might get involved in an inappropriate teacher-student relationship a la Kim and Mr. Matthews.

After all: Everyone's hot for teacher these days.

Did you like Jessica as Kim?
