Sometimes truth is stranger than fiction. 

It's an old adage, one Kevin Costner says holds especially true in the story of the untamed American frontier.

The "Field of Dreams" and "Dances with Wolves" legend brings this idea to life in "Yellowstone to Yosemite," a new three-part Fox Nation series that explores how a seemingly unrelated string of events set the stage for one of the most pivotal moments in American history.

"It's a story about a confluence of tragic events separated by time and space intersecting in a seemingly impossible manner. And somehow something incredible came out of all of it," Costner explained.

"A young boy suffering from severe asthma, a president's assassination, a horrible accident at a wagon wheel factory – unrelated events in most people's minds, but they all needed to happen for this story to unfold, for two men to come together for three days out in the wild. Three days that would change America forever…"

FOX NATION TO PREMIERE ‘YELLOWSTONE TO YOSEMITE’ WITH KEVIN COSTNER

"That's a story worth telling, don't you think?"

Costner teamed up with the Fox Nation platform for "Yellowstone to Yosemite" following the success of his breakout hit, "Yellowstone: One-Fifty."

Through the Hollywood legend's distinctive perspective, the new series traces the footsteps of President Teddy Roosevelt and environmental advocate John Muir's pivotal 1903 Yosemite expedition.

In the process, he brings to life the story of America's indigenous legacy, the outsiders that came along and how Muir became a crusader for America's wildest places.

"Two men embark on a camping trip. These two men have never met before. They pushed through heavy snow, get soaked with rain and wash down steaks with hot coffee," he explained.

"They didn't set out to change America, but what they dreamed up around the campfire – some might call it ingenious. Others might say cunning. But, boy, did it work."

The elements of the tale, all essential to preserving the captivating story of the American frontier, led to America's more structured National Park System today – 150 National Forests, five National Parks, along with the preservation and protection of 230 million acres of land.

The series debuted on the Fox Nation platform over the weekend, with new episodes dropping each week.

Kevin Costner's ex-wife, Christine Baumgartner, is reportedly off the market.

The purse designer, who finalized her divorce from the "Yellowstone" star in February 2024, is engaged to financier Joshua Connor, according to People magazine.

Romance rumors between Baumgartner and Connor sparked in July 2023 when the couple was spotted on vacation in Hawaii.

Nearly one year later, the pair confirmed their relationship while walking hand-in-hand together in Santa Barbara, California, shortly after she finalized her divorce with Costner.

Connor reportedly proposed after an intimate dinner in Santa Barbara, California. "It was about to rain, so almost no one else was on the beach when Josh got down on one knee," a source told the outlet.

Representatives for Costner did not immediately respond to Fox News Digital's request for comment.

Baumgartner filed for divorce on May 1, 2023, citing irreconcilable differences. In documents obtained by Fox News Digital, Christine cited April 11 as the date of separation. 

She initially requested $248,000 in monthly child support for their three children, and a judge set a temporary monthly sum of $129,755 in July, only to rule in September that Costner would be responsible for $63,209 in monthly child support payments.

Connor's name became a focal point during Baumgartner and Costner's child custody payment hearing last year when Costner's legal team called into question a $20,000 loan from a "boyfriend" who they named as Josh.

Fox News Digital was in the courthouse when Baumgarter took the stand and said Connor was a longtime friend of "seven or eight years." When Rydell asked, "Is he your boyfriend?" Baumgartner replied, "No."

She recalled traveling to Hawaii in March with Connor and his daughter, and a group of friends. Costner didn’t go because "he wanted to do a speech with a hunting club." The Costners paid for the vacation home where the families stayed.

On July, Baumgartner traveled back to Hawaii with a group of friends and their children, including Connor and his daughter, who is "best friends" with Grace Costner, 13. Baumgartner said Connor "paid for the house."

When Rydell asked about claims Connor "gave Christine money," she said, "I can’t remember if it was before or after (the March or July trips to Hawaii.)" She continued, "He gave me $20,000." 

Of the $20,000, the purse designer said, "I gave $10,000 to my mother." She then became emotional on the stand. "She was concerned about her house," Baumgartner noted.

Hollywood heavyweight Kevin Costner is teaming up with Fox Nation once again for a new limited series titled "Yellowstone to Yosemite," a sequel to his breakout hit, "Yellowstone: One-Fifty."

"Kevin Costner has a unique ability to capture the American experience and captivate an audience through his extraordinary storytelling," Fox Nation President Lauren Petterson said while announcing the partnership.

The "Dances with Wolves" and "Field of Dreams" star will host and produce the 3-part series that traces the footsteps of 26th President Teddy Roosevelt and environmental advocate John Muir's pivotal 1903 Yosemite expedition.

In the process, he brings to life the story of America's indigenous legacy, the outsiders that came along and how Muir became a crusader for America's wildest places.

These elements, all essential to preserving the captivating story of the American frontier, led to where America's more structured National Park System is today – 150 National Forests, five National Parks, along with the preservation and protection of 230 million acres of land.

"Once in a while, you come across a story that has that truly special mix of elements; it's stranger than fiction and happens against all odds. It results in something that legitimately changes the world for the good and, most importantly, it all really happened," Costner said, speaking to its allure.

"The story of President Teddy Roosevelt and John Muir's camping trip through Yosemite is one of those truly special ones, and I'm excited to dig into the next chapter of the preservation of the American frontier."

Baumgartner filed for divorce in May 2023. The two went through a bitter court battle over custody of their children, with Costner coming out on top. Baumgartner and the actor finalized their divorce in February 2024.

Before the former couple signed a settlement agreement, Costner told Fox News Digital there are no winners in their divorce battle.

"You know, when you have a life that long with somebody, there is no winner … and it's this big, crazy thing called life and how it unravels so quickly," he said. "One minute you feel like you're on top of the world, and then you realize how … vulnerable you are."
