• Dax Shepard shared a snap of his wife Kristen Bell hugging Luke Grimes 
  • He joked that his marriage with Bell is over now that she's met the "Yellowstone" star
  • Bell said her husband doesn't have to worry about divorce but joked that he would have to accept a third person in their marriage

Dax Shepard joked about his wife Kristen Bell leaving him after she met the star of one of her favorite TV series.

On Sunday, Shepard shared on Instagram a snap of the "Veronica Mars" star hugging Luke Grimes. Bell gave a slight smile in the photo, while Grimes looked pensive and brooding — very much like his "Yellowstone" character, Kayce Dutton.

"Well, that's a wrap on my marriage!" Shepard wrote in the caption. "I wish you both well, and I don't blame either of you. Fair play @lukegrimes."

Shepard's fans and followers were amused by his post and began poking fun at the 47-year-old actor, with one commenting: "You’re irresistible, but he is too! Lol. Long live #Daxstin!"

"I mean, we really can’t blame her at all," a second user wrote. "Ahhhh the sweet sting when they upgrade," another netizen jokingly commented.

"No s--t. Sorry, Dax. But you can still be a great weekend dad," another joked, adding laughing emojis.

Many commenters also praised Shepard and Bell's relationship.

"She would never leave you. Happy Easter, buddy," one fan wrote, while another commented, "Too bad you two are like a puzzle. Without one or the other, the puzzle would never be complete. Together you two complete the puzzle."

Bell shared the photo of her and Grimes on her Instagram account the following day, revealing that her husband didn’t have to worry about a divorce. She joked that Shepard just had to accept a third person in their marriage.

"Sister wives? Nah, let's go with Brother husbands," the "Frozen" star wrote. "@lukegrimes welcome to the family and @daxshepard, as usual, thank you for being so supportive. We’re all Duttons now!!"

The show's official account chimed in, commenting on the post: "Welcome to the Yellowstone."

"@yellowstone I’m thrilled to be here. Pls saddle up my horse," Bell replied.

Grimes, who previously worked with Shepard on the 2017 Netflix comedy "El Camino Christmas," has been married to model Bianca Rodrigues Grimes since 2018, according to Us Weekly.

Meanwhile, Bell and Shepard exchanged vows in a courthouse ceremony in 2013 and share daughters Lincoln, 9, and Delta, 7.

Bell is just as supportive of her husband's celebrity "crushes."

The "Armchair Expert" podcast host revealed on "The Ellen DeGeneres Show" in November 2021 that after years of having a man crush on Brad Pitt, he's found a new crush in Australian Formula One driver Daniel Ricciardo.

Shepard shared that after the race car driver appeared on his podcast, they "kind of hit it off" and eventually became inseparable.

"We've just really been building this thing that’s culminated in us seeing the world together, really," Shepard said.

Bell told talk show host Ellen DeGeneres that Shepard and Ricciardo are "really cute" and that she "fully" supports their bromance.
