Yellowstone actor Luke Grimes and his wife Bianca Rodrigues have shared their first family photo with their newborn –

eight days after welcoming a baby boy.

Taking to Instagram, Brazilian model Bianca shared the adorable family portrait of herself being held in Luke’s arms, holding their son captioned: “And then there were 3.”

The sweet update was met with an abundance of congratulatory messages, many from Luke’s Yellowstone co-stars.

“Crying ❤️ so precious,” wrote Kathryn Kelly, who plays Emily, Jimmy’s love interest in the series.

“What a great family photo. Congratulations to you both, what a lucky little boy you have ❤️,” said another follower.

While Hassie Harrison and Ian Bohen left a string of love heart and proud face emojis.

Luke and Bianca announced the arrival of their first child together on October 10, 2024.

“Welcome to the world little man 💙,” Bianca captioned a photo of herself cradling their newborn.

The pair have yet to confirm the tot’s name.

The first-time parents tied the knot in November 2018 and moved to Montana, which is where Yellowstone is filmed. Luke plays Kayce Dutton in the hit western series.

In 2022, Luke spoke to ET about his relationship and how “lucky” he felt to be with his wife.

“I’m happy with my life, you know,” he said. “I wake up every day and feel so lucky…I get to live where I live and be married to my wife. So yeah, sure, I’m proud of myself.”

Luke has just finished filming the last episodes of Yellowstone, which will air on Stan in November.

This month he told Newsweek that the show was “not at all” easy to say goodbye to.

“I finished shooting over a month ago and I’m still sort of processing all of that and I still have moments of the day where it feels very heavy and very big that that’s over,” he explained.

“I played that character for seven years, since 2017. My cast mates and the crew became like another family. “It was such a special project and I doubt it will ever be topped in my life.”
