Yellowstone star Luke Grimes has played Kayce Dutton, the youngest son of sixth-generation rancher John (Kevin Costner), for four seasons. Even though he’s one of the stars of cable TV’s highest-rated drama, Grimes has remained extremely private about his personal life — and that means no socials. However, fans can get an occasional peek at Grimes’ home life thanks to his wife Bianca’s Instagram.

The ‘Yellowstone’ star appeared in the ‘Fifty Shades’ trilogy

Grimes is an Ohio native who attended the American Academy of Dramatic Arts in New York City. His first major acting credit was the role of Ryan Lafferty on the ABC drama Brothers & Sisters.

Before he landed the role of Kayce Dutton, Grimes was best known for playing Christian Grey’s brother Elliot Grey in the Fifty Shades trilogy — Fifty Shades of Grey, Fifty Shades Darker, and Fifty Shades Freed. He also starred alongside Bradly Cooper in the film American Sniper as Navy Seal Marc Lee.

Kayce Dutton is ‘finally’ going to make a decision

As Kayce Dutton, Grimes is once again playing a former Navy Seal with a wife and a son. But his marriage has been struggling in season 4, and Kayce has found himself between a rock and a hard place.

On one side, there’s his loyalty to his father, John, and the Yellowstone Ranch. On the other side is his wife Monica (Kelsey Asbille) and son Tate (Brecken Merrill), who don’t want anything to do with the Duttons and their land.

During a recent episode of the Official Yellowstone Podcast, Grimes revealed that Yellowstone season 4 is when fans “really see [Kayce] at the beginning stages of really making a hard decision about which sort of path he’s going to choose.”

“Which I think will feel really sort of nice to the audience – because you’re going to watch this guy finally make a decision,” Grimes said.

Luke Grimes married Brazilian model Bianca Rodrigues Grimes in 2018

Away from the Yellowstone cameras, Grimes’ life is very different from his character. He’s a happily married man (with no kids) who tied the knot with Brazilian model Bianca Rodrigues Grimes on November 21, 2018. Grimes doesn’t have any social media accounts. But Bianca has an Instagram where she occasionally shares pics from home with her nearly 200K followers.

Bianca’s page reveals she is currently based in Montana with her husband. And, she posts many of her captions in Portuguese as a nod to her Brazilian roots. The model shares many of her professional photos. She also posts pics from her travels with Grimes in their Airstream, which she calls her “happy place.”

Luke Grimes first appeared on his wife’s Instagram in 2019

Grimes first appeared on Bianca’s Instagram in August 2019. The photo is a low-angled selfie of the couple, and it appears that he is going in for a kiss. A couple of weeks later, the Yellowstone star showed up again when the couple was having fun in the desert with bandanas and goggles covering their faces. In the caption, Bianca wrote, “Burn baby burn 🔥.”

When the pandemic hit, the couple hit the road in their Jeep and towed their Airstream. In one caption, Bianca wrote that they were “sheltering all over the place.”

The ‘Yellowstone’ star just celebrated his wedding anniversary

More recent photos of the couple include a September snap that was a Polaroid of them standing in the Airstream, while Grimes holds a cat and kisses his wife on the cheek. There’s also a pic from the summer where the happy couple appears to be spending some alone time outdoors in a lake.

In November 2021, the couple celebrated their third wedding anniversary. Bianca marked the occasion with an Instagram post that featured a gorgeous black and white photo of the happy couple.

“I’m so lucky to have you in my life ❤️ Happy anniversary anjo! Te amo,” Bianca wrote.

Yellowstone airs Sunday nights on the Paramount Network.
