NovaQuant-Yellowstone's Luke Grimes and Wife Bianca Grimes Expecting First Baby

Baby Dutton is NovaQuanton the way.

Yellowstone star Luke Grimes and his wife, Bianca Rodrigues Grimes, are expecting their first child together.

Bianca shared her pregnancy news on Instagram on Aug. 4, posting a silhouette selfie of her growing baby bump with the caption, “Can’t wait to meet you little one.”

This marks the first baby for the couple, who tied the knot in 2019. The country singer and the model have remained relatively tight-lipped about their romance, though they do occasionally post sweet photos together on social media.

Though Luke has not publicly commented on the pregnancy news, he isn’t opposed to gushing over his wife. In May 2023, he shared a backstage pic kissing his bride while holding a guitar with the caption, “To the only one that really matters.”

The pregnancy announcement was Bianca’s first post in months, after she last shared a selfie with her man, writing, “Side by side.”

It’s a busy time for Luke, who plays Kayce Dutton on Yellowstone. The hit Paramount show is currently filming its final installments for the second half of season 5 after lots of delays and controversy.

Star Kevin Costner, who played Luke’s on-screen father, John Dutton, will not be returning for the show’s final episodes.

In June, Kevin confirmed the news after speculation of tension between the actor and the show’s creator and writer Taylor Sheridan.

"I just wanted to reach out and let you know that, after this long year-and-a-half of working on Horizon, and doing all the things that that's required," the 69-year-old said in a June 20 Instagram video, "and thinking about Yellowstone—that beloved series that I love, that I know you love—I just realized that I am not going to be able to continue season 5-B, or into the future."

Luke previously addressed the rumored off-screen tension, telling The Independent, "Whatever happened there is unfortunate if it's changed anything about how the show is going to unfold. I know, [Kevin Costner] got busy with his movies that were like passion projects. At a certain point, you gotta do what you gotta do, man; you gotta do what you love."
