Jennifer Garner wowed on the red carpet at the Los Angeles premiere of her latest project Thursday, and she brought someone special to share the big night.

The actress, 50, who enthusiastically promoted the Apple TV+ series The Last Thing He Told Me, looked stunning in a white strapless dress with black vertical lines.

Her auburn bob was styled back from her face in loose waves as she signed autographs for waiting fans.

As the leading lady posed on the red carpet with co-star Aisha Tyler, 52, executive producer Reese Witherspoon, 47, and author Laura Dave, 45, USA weekly reported that Jennifer’s old beau, John Miller, quietly arrived at the theater to support her.

The source revealed that the Party Down star “glow” as she walked into the theater, and that the CEO of Caliburger sat a few rows behind her during the screening.

The couple has been linked to each other since 2018, but keeps their relationship quiet. They are rarely seen together in public.

In the limited series, based on the book of the same name, Jennifer stars as Hannah.

When her husband mysteriously disappears, Hannah receives a note from her husband asking her to protect his daughter Bailey, played by Angourie Rice, 22.

The Yes Day star, who is mum to Violet, 17, Seraphina, 14, and Sam, 11, from her marriage to Ben Affleck, 50, told Collider that “playing the stepmother of someone who isn’t happy to have you as a stepmother was something that really intrigued me.”

In an interview with Peoplethe Alias ​​star argued, “The teen in the story, Bailey, played by the beautiful Angourie Rice, she’s a completely different…she’s mean.”

My kids aren’t mean β€” they’re teenagers, but they’re not mean, adding, “Not to me.”

“So that was funny,” she continued, “just another layer of teens to deal with.”

The experience was very different from the day-to-day dealings with her own teenagers.
