COWBOY MATT HOLDS OUT FOR 10-GALLON PAYCHECK!

Plays hardball to take reins of Yellowstone spinoff

- 

MACHO movie star Matthew McConaughey is holding the Yellowstone producers' feet to the fire, demanding a geyser of greenbacks for taking over as the new face of the popular TV franchise!

Sources snitch the 54-year-old believes he's the key to the success of the proposed new spinoff and wants Kevin Costner-type cash - but producers are balking and that could delay production or kill the whole deal!

"Matthew and his team know he's the number one creative choice for the post-Kevin Costner version of Yellowstone that's being planned, but Paramount is dragging its feet on his $2.5 million per episode asking price and there's a real possibility Matthew will just move on," spills an insider.
