Watch Katherine Heigl and Alexis Bledel as a Couple in the Trailer for Jenny’s Wedding

Katherine Heigl is starring in another wedding movie, but this time the premise is quite different from 27 Dresses. In Jenny’s Wedding, Heigl plays a lesbian whose family has been in the dark about her sexual orientation, and when they find out she plans to marry her partner, played by Alexis Bledel, they’re blown away that two have been more than roommates all these years—and not very quick to accept the news.

Tom Wilkinson, Linda Emond and Grace Gummer round out the cast of the film, which opens in theaters July 31.
