KELLY & COLE HOG-TYING YELLOWSTONE SPINOFF

Swollen-headed stars want to blaze a trail away from Costner

- 

KEVIN COSTNER may have departed Yellowstone, but series creator Taylor Sheridan still has two demanding divas on his hands: Kelly Reilly and Cole Hauser.

The duo, who have been dubbed the gruesome twosome, is pressuring Taylor not to cast another big name in the next spinoff because they want to be the sole stars, a show insider says.

But the two, who know they are now the highest-profile cast members, plan to squeeze him for bigger bucks.

“It’s causing a ruckus among the other cast and crew, who think Kelly and Cole are getting greedy and big-headed,” says a snitch.
