Which actress played Becky Slater, Kevin's one-time girlfriend on The Wonder Years?

Crystal McKellar played Becky Slater, Kevin’s one-time girlfriend on The Wonder Years.

Becky Slater appears as a recurring character in the series’ second season. Kevin Arnold dates her partly to make Winnie Cooper jealous, but Becky discovers that Kevin still has feelings for Winnie. Her anger leads to a memorable confrontation and helps establish her as one of Kevin’s more intimidating junior-high acquaintances.

The role has an especially interesting connection to the show: Crystal McKellar is the older sister of Danica McKellar, who played Winnie Cooper. The sisters had both attended the Diane Hill Hardin Young Actors Space school and sometimes competed for acting roles. Their casting created a real-life family link between the series’ central romantic triangle.

A common mix-up is confusing Crystal with Danica. Danica played Winnie, Kevin’s best-known love interest, while Crystal played Becky. Crystal later moved away from acting, pursuing economics at Yale, law at Harvard, and a career as an attorney and venture-capital investor.
