Luke Grimes may be known to audiences for playing Kayce Dutton in Yellowstone and its spinoff Marshals, but the actor has kept much of his personal life away from the spotlight. His relationship with Brazilian model Bianca Rodrigues Grimes is one part of his life he occasionally shares, offering glimpses into a marriage that began just months after their first meeting.

The couple met on the dating app Raya and married in November 2019, reportedly just four months after their first date. They welcomed their first child, a son, in October 2024, and are now approaching another wedding anniversary.

During an October 2026 appearance on Live with Kelly and Mark, Luke hinted that he was preparing something special for the occasion but kept the details private.

“I can’t tell you then my wife will find out,” he joked. “I got some plans. I got something special [lined up].”

Here is what to know about Bianca Rodrigues Grimes and her relationship with the Yellowstone actor.

She Is a Brazilian Model

Bianca is originally from Brazil and works as a model. Although she now resides in Montana while Luke films the Yellowstone spinoff Marshals in Utah, she has maintained a relatively low public profile.

Her Instagram account occasionally offers a look at her modeling work, featuring both beach photography and studio portraits inspired by classic Hollywood glamour. She also shares personal moments with Luke and their son, giving followers a glimpse of their family life.

They Met on the Dating App Raya

Luke and Bianca’s relationship began with a dating-app match. During a March 2026 appearance on The Drew Barrymore Show, the actor revealed that they met through Raya, an experience he had not expected to have.

“I know that’s crazy. I never thought I’d be on a dating app to begin with,” he said. “My wife was my first date, and we were married in four months.”

Luke explained that meeting Bianca changed how he viewed the rest of his life. “I didn’t think there was any chance, but honestly, since meeting her, everything else in my life has sort of right-sized,” he said. “I found the thing that I didn’t know [that] I was looking for. And now everything else is just sort of a cherry on top.”

He later joked that joining the app was the “best $20 I ever spent.”

During his October 2026 appearance on Live with Kelly and Mark, Luke recalled that he knew he was interested in Bianca almost immediately, although it took some time to win her over.

“I was in right away,” he said. “I had to spend a few months convincing her that I wasn’t crazy and sort of wooing her. But I knew right away. I was smitten.”

Bianca offered an early glimpse of their relationship on Instagram in August 2019, sharing a photo with Luke accompanied by sparkle and heart emojis. Less than two weeks later, she posted another picture of them wearing bandanas and goggles in the desert, captioned “Burn baby burn 🔥.”

They Married in November 2019

The couple reportedly married on Nov. 21, 2019. Bianca has marked the occasion with anniversary tributes on social media over the years.

For their third anniversary in November 2022, she shared a photo of Luke kissing her cheek and wrote, “3 years married to my favorite person in the world ❤️ Te amo ❤️.”

In a previous anniversary post, she shared a black-and-white beach photo of the two of them, accompanied by the message, “I’m so lucky to have you in my life ❤️ Happy anniversary anjo! Te amo.” The Portuguese word “anjo” means “angel.”

Luke has also spoken warmly about his marriage. In a July 2023 interview with USA TODAY, he described himself as deeply devoted to Bianca.

“I’m a very married person and I love my wife to death. We’ll be together forever,” he said. “There’s no way I earn it. I do my best. But I’m a flawed big ol’ weird-ass man. She’s the real angel here.”

They Welcomed Their First Child in 2024

Luke and Bianca became parents in October 2024, when they welcomed a baby boy. Bianca announced the news on Instagram with a photograph of the couple and their newborn, writing, “And then there were 3.”

Luke has since shared a few details about life with their son. During an appearance on Live with Kelly and Mark, he described the toddler’s interests, including music, balls and toy trucks.

“He loves music. He loves balls,” Luke said. “Anything round he’s [throwing it]. He likes little toy trucks. He’s just you know, he’s all boy running around crazy.”

While the actor and model continue to keep much of their family life private, their occasional comments and social media posts show the affection they share. With another anniversary approaching, Luke’s promise of a special surprise offers a small glimpse into how he continues to celebrate their relationship.
