Hold your horses.

“Yellowstone” actor Jefferson White is not sure if one of the cowboy franchise’s hotly anticipated spinoff shows is still happening.

White recently told The Daily Mail, “Not that I know of now,” when asked if he’ll reprise his role for the planned spinoff “6666.”

“I kept my fingers crossed, but also, I’d be grateful if I got to do more and I’m grateful for what I got to do. I don’t want to be selfish,” he said. “We got a lot of great mileage out of that show.”

The Post reached out to Paramount for comment.

Paramount announced the show “6666” in Feb. 2021. Set on Texas’ historic Four Sixes Ranch – which “Yellowstone” mastermind Taylor Sheridan bought in real life – the show would follow Jimmy (White) after the events of “Yellowstone.”

Since 2022, Sheridan has owned that iconic ranch. It’s famous in cowboy circles, and it was controlled by a family dynasty for over a century.

Per the Austin American Statesman, Sheridan buying the 266,000-acre property marked its first-ever purchase since its founding in 1870.

“Yellowstone” aired for five seasons on Paramount from 2018 to 2024, ending amid rumors of an alleged feud between Sheridan and star Kevin Costner. The plot centered on the Dutton family, including patriarch John (Costner) and his adult children Kayce (Luke Grimes), Jamie (Wes Bentley), Beth (Kelly Reilly) and Beth’s husband, Rip (Cole Hauser).

There’s a spinoff in the works for Kayce called “Y:Marshalls” premiering on CBS in March. There’s also a Beth and Rip spinoff in the works. Rumored to be called “The Dutton Ranch,” it premieres at an unannounced date in 2026.

However, “6666” was also in the works, but according to White, he’s heard crickets about it.

Matters have also been complicated with the shocking news that Sheridan is exiting Paramount to sign an NBCUniversal deal reportedly worth $1 billion.

His TV deal with Paramount doesn’t officially end until 2028, and future shows in the “Yellowstone” world will still live on Paramount – but perhaps he doesn’t have much incentive amid the move.

“I grew up in the shadow of the Four Sixes,” he told The Hollywood Reporter in 2023.

“To just get one of their horses was a status symbol, because they’re so well trained,” he explained. “This was the ranch I based [‘Yellowstone’s’] scope and operation on, because it didn’t exist in Montana. Most ranches there had already been carved up. They’d already lost it.”
