Did Hubbell and Katie have a child?

Yes, in The Way We Were, Hubbell Gardiner played by Robert Redford and Katie Morosky played by Barbra Streisand do have a child together during their marriage before they divorce. The film follows their relationship from college in the late 1930s through their marriage in the 1940s and early 1950s and their eventual divorce due to political differences during the Hollywood blacklist era and Hubbell's infidelity. During their marriage, Katie becomes pregnant and they have a daughter, which is shown as a hopeful moment in their relationship. However, even having a child cannot save their marriage because their fundamental differences in values remain: Katie is passionate and political, while Hubbell is charming but avoids commitment and principles. After their divorce, Katie takes primary custody of their daughter and moves on with her life, later remarrying and raising the child with her new husband. In the film's iconic final scene set years later in front of the Plaza Hotel in New York, Katie is seen with her daughter and new husband while Hubbell is with a new girlfriend, and someone remarks Your girl is lovely, Hubbell, referring to the daughter who is Hubbell's biological child but whom he is not actively raising, highlighting the bittersweet aftermath of their love story.
