“Can’t wait to meet you, little one.”

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

Rodrigues returned to Instagram after a social media break to share a picture of her silhouette where her baby bump is in full display.

“Can’t wait to meet you, little one,” the model captioned the shot, adding a red heart emoji.

Grimes is yet to share the happy news on his own social media.

The couple tied the knot in 2018, with the actor and musician often paying sweet tributes to his wife throughout the years. In May 2023, Grimes took to Instagram to share a black-and-white shot with Rodrigues on the side of the stage during one of his concerts.

“To the only one that really matters,” he wrote in the caption.

Earlier this year, Grimes commented on Kevin Costner’s Yellowstone exit after it was announced that the John Dutton star wouldn’t return for the fifth and final season.

“Whatever happened there is unfortunate if it’s changed anything about how the show was going to unfold,” Grimes, who plays Kayce Dutton on the show, told The Independent in April.

Grimes said he understood his co-star’s decision, said to be motivated by Costner’s desire to focus on his film Horizon: An American Saga.

“I know, [Costner] got busy with his movies that were like passion projects,” Grimes said. “At a certain point, you gotta do what you gotta do, man. You gotta do what you love.”

Last month, Josh Lucas, who plays the younger version of John Dutton, shared his engagement to his partner Brianna Ruffalo.
