Freddie Prinze Jr. shared how friendship and respect nourish his 23-year marriage with Sarah Michelle Gellar, whom he met on the set of the 1997 film "I Know What You Did Last Summer."

Freddie Prinze Jr. and Sarah Michelle Gellar are more than just a throwback to your early-2000s movie nights—they’re also one of Hollywood’s longest-running love stories. They’ve survived killers with hooks, horrifying monsters, and the worst thing of all: high school.

Prinze Jr., who is currently starring in the sequel to I Know What You Did Last Summer, shared that his relationship with the Buffy the Vampire Slayer star and their two children, Charlotte, 15, and Rocky, 12, are his most cherished accomplishments.

Prinze and Hewitt, 46, are set to return to the franchise with the new I Know What You Did Last Summer reboot.
