The perfect pair enjoyed a date night at a screening of their new movie, The Book of Love, at the New Orleans Film Festival on Saturday.
Biel looked stunning in a skin-tight olive green leather mini dress while Timberlake rocked a casual charcoal blazer, dark jeans, a blue button-down shirt and his signature fedora as they smiled for photographers on the red carpet.
Biel later Instagrammed a selfie with her husband and the Purples to celebrate the film's "homecoming" in New Orleans.
The cute couple's fourth wedding anniversary is just around the corner on Oct. 19, but the dynamic duo celebrated early with a low-key date night last Thursday, which included a game of Scrabble and a few glasses of wine.
Earlier this month, Timberlake sat down with the Today show and got emotional while opening up about how being a father and a husband has "changed everything" for him. Check out the heartfelt interview in the video below.
The Book of Love, which also stars Jason Sudeikis, Maisie Williams, Orlando Jones, Mary Steenburgen and Paul Reiser, hits theaters Jan. 13, 2017.
