“Can’t wait to meet you little one ,” she wrote via Instagram on August 4.

Although Luke became a household name thanks to his role as rancher Kayce Dutton on the hugely popular Western drama Yellowstone, his personal life has stayed very much private.

Social media, however, has provided some clues into his love story with Bianca ever since they got married in November 2018.

According to Instagram, the couple reside in Montana for much of the year as Yellowstone films in the state. Before becoming parents, both Luke and Bianca also shared two Bengal cats, Buck and Zelda.

While Luke previously joked that he’s “allergic” to Instagram and doesn’t even want the password, the actor was able to gush about his wife in a rare interview.

“I just wanted to make it very clear. I’m a very married person and I love my wife to death,” he told USA Today in July 2023 after posting a rare couple’s shot from the Stagecoach Music Festival online. “We’ll be together forever.”

He added that his wife calls him “anjo,” the Portuguese word for angel.

“There’s no way I earn it,” he continued. “I do my best. But I’m a flawed big ol’ weird-ass man. She’s the real angel here.”

In November 2021, Bianca took time to celebrate her wedding anniversary with Luke by sharing a throwback photo from a date night. She summed up her feelings on their love story by writing, “I’m so lucky to have you in my life Happy anniversary anjo! Te amo.”

As Luke and Bianca settle into parenthood, fans can look forward to the final episodes of Yellowstone unfolding on the Paramount Network starting in November.
