Luke Grimes is a man of many cowboy hats. Besides playing the role of Kayce Dutton on the hit Paramount Network show Yellowstone — and leading the Marshals spinoff — he is also a singer-songwriter, husband and father.

The actor has been married to his wife, Brazilian model Bianca Rodrigues Grimes, since November 2019. The two share a son, who was born in October 2024.

 

 

The actor has been married to his wife, Brazilian model Bianca Rodrigues Grimes, since November 2019. The two share a son, who was born in October 2024.

Bianca first posted her actor beau via her Instagram account in August 2019 with a photo of them getting cozy in the sunshine. The model didn’t say much else, with her caption showing just a sparkle emoji and a heart emoji.

At the end of the month, she posted a second photo of the two of them wearing goggles in the desert, with the caption “Burn baby burn 🔥”.

“I’m so lucky to have you in my life ❤️ Happy anniversary anjo! Te amo,” Bianca wrote via Instagram in November 2021, sharing a sweet never-before-seen photo of the couple.

The couple made multiple red carpet appearances in 2022, including at the Screen Actors Guild Awards and the Academy of Country Music Awards in addition to hitting the Yellowstone season 5 premiere event together.

“Thank you @acmawards for having us ❤️ dream come true night,” Bianca posted in March 2022 after the ACMs.

Later that year, Bianca celebrated “3 years married to my favorite person in the world” with a sweet Instagram tribute to Luke in November 2022.

“I just wanted to make it very clear. I’m a very married person and I love my wife to death,” he told the outlet at the time. “We’ll be together forever.”

Luke added: “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.”

Bianca, meanwhile, proved she is a big supporter of Luke’s musical career, sharing moments of him in concert throughout 2023. Luke, for his part, posted a photo in May 2023 of his wife kissing him backstage at a show, writing, “To the only one that really matters.”

The year 2024 saw big changes for the couple. In August 2024, Bianca announced that she was pregnant with their first baby. “Can’t wait to meet you little one ❤️” she wrote via Instagram alongside a selfie of her baby bump.

In October 2024, the couple welcomed a baby boy, with the model writing “Welcome to the world little man” via her instagram. One week later, Bianca shared a picture of their family of three.

The following month, the pair took their son to support Luke during one of his concerts, captioning a sweet photo of the three of them: “Daddy played the Ryman!!!”

“2024 was the greatest year of my life. Here is the proof,” Luke captioned his own photo from the Ryman performance with his wife and child.

The couple had a quieter year, soaking up their new normal as parents. Bianca, however, gave fans a glimpse at their home life via Instagram in September 2025 on their son’s first birthday.

“Greatest year of my life 🩵✨,” she captioned a picture of the trio with cake and streamers with their baby’s face on them.

Luke kicked off the new year by walking the 2026 Golden Globe Awards red carpet solo. The January event marked the official countdown for Yellowstone fans to the spinoff series Marshals, which premieres in March 2026, and focuses on Luke’s character, Kayce Dutton.
