Luke Grimes captivated audiences as rancher Kayce Dutton on Yellowstone beginning in 2018, and while his character’s love story with Kelsey Asbille’s Monica is one fans always rooted for, it’s his off camera romance that is even more magical.
The actor, whose spinoff Marshals premieres in March 2026, has been married to wife Bianca Rodrigues Grimes since 2019. While Luke has kept much of their relationship out of the limelight he gushed about his partner in July 2023, telling USA Today, “I’m a very married person and I love my wife to death.”
He promised, “We’ll be together forever. 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, for her part, has shared glimpses of their romance via Instagram. She frequently calls Luke her “anjo,” which means “angel” in Portuguese, and posts pictures from their time traveling across the U.S.

“She moved to the States without knowing a word of English,” Luke told People of his wife in July 2023. “And when I met her, she had only lived here for two years but she spoke beautiful, fluent English. I was like, ‘How did you learn it so fast?’ And she said, ‘I watched The Office with subtitles.’”

According to Luke, Bianca’s love of Montana is what sparked their move from Texas. “She came up with me for work one year [on Yellowstone] and just sort of fell in love with it, and we kind of got into the rhythm up there,” Luke said during a January 2023 episode of the Today show. “Going back to Texas didn’t sound like much fun so we stayed, we built a house.”
Since settling down in Montana, Bianca has documented her and Luke’s adventures in nature, including camping in nearby Wyoming, kayaking on the lake, rock climbing, hiking and swimming under waterfalls.
