Amanda Seyfried Debuts as Tiffany & Co. Ambassador in Holiday 2026 Campaign

Amanda Seyfried is now officially part of the Tiffany & Co. family. The jeweler named her its newest House ambassador on October 28, and she makes her debut in the holiday 2026 campaign, "Love Is a Gift."

The star of the season is "You & Me," a two-minute film directed by Derek Cianfrance and created with agency American Haiku. It jumps between present-day New York and a Christmas memory from the 1990s, following a hand-painted Bird on a Rock ornament as it's passed down through three generations. Seyfried plays the mom this time, which is a fun twist if you still think of her as the daughter in Mamma Mia!

Seyfried keeps the wardrobe basic, all black. One shot has her in a fuzzy knit turtleneck, the others in a sleeveless dress with a draped neckline. The jewelry is where the sparkle comes in. She wears HardWear by Tiffany, the chunky 18k gold links with hand-set pavé diamonds, and the necklace rests right on top of that turtleneck collar. Matching link drop earrings peek out from her hair. Another frame adds a gold link bracelet and a diamond ring as she holds a Tiffany Blue Box with a white ribbon. Her blonde hair is pulled back low, with a couple of loose strands falling around her face. Want to try the hair color? Our golden blonde hair shades guide shows how celebrities wear it.

That quiet styling fits the story. The film follows a daughter who starts seeing her mother as a woman with a life beyond parenting, and a Blue Box marked "December '92" pulls that memory back before the ornament inside moves on to the next generation. It's a sweet, nostalgic take on holiday gifting, and the shiny gold does the dressing up.

Seyfried also fits right in with our list of famous blonde actresses who've made their mark on screen and on the red carpet.
