The actress says several young stars want to join the iconic musical franchise — and she’s fully behind expanding the cast.

Seyfried Envisions a New Generation of Mamma Mia! Stars

November 19, 2025: Amanda Seyfried is ready to return to the sun-soaked world of Mamma Mia! — and she’s already imagining the next generation of talent joining her. In a recent interview, the Oscar-nominated actress revealed that she would love to see Sydney Sweeney and Sabrina Carpenter star in the long-anticipated Mamma Mia 3.

Seyfried, who has portrayed Sophie since 2008, said she’s excited about welcoming new women into the beloved franchise. She shared that “a bunch of girls want to be part of it,” and she’s thrilled about the possibility of expanding the cast with young, energetic talent.

Sophie as a Mom? Seyfried Has Ideas

Seyfried shared that she already has a vision for how the characters could evolve. She suggested that her character Sophie could now be a mother, opening up new storylines and character dynamics. She floated the idea of Sabrina Carpenter playing Sophie’s cousin and Sydney Sweeney taking on a fresh, central role.

Her enthusiasm stems from wanting to keep the franchise vibrant while honoring the heart of the original films — music, family, and sunlit escapism.

A Third Film Feels Within Reach

While Mamma Mia 3 has not yet been officially confirmed, Seyfried remains optimistic. She noted that the team and cast are eager, the fans are passionate, and there is no shortage of story potential. According to her, a new movie feels less like a question of “if” and more like “when.”

Her confidence has reignited fan excitement, especially with the idea of bringing in popular young stars who are already known for their charisma, music talent, and screen presence.

Fans Embrace the Idea

The thought of Sydney Sweeney and Sabrina Carpenter joining the franchise has sparked major buzz online. Sweeney has expressed interest in the series before, and Carpenter — who has a strong musical background — feels like a natural fit for the ABBA-filled universe.

With Seyfried championing their involvement, fans are hopeful this dream lineup could become a reality.
