CATWOMAN MICHELLE SINKS HER CLAWS INTO YELLOWSTONE!

CRANKY Kevin Costner and meandering Matthew McConaughey are both jockeying for position to be the overlord of Yellowstone, but there's growing talk Michelle Pfeiffer will knock them both off their pedestals and become the franchise's undisputed cowboy queen leaving the high-profile guys playing second fiddle!

"Michelle is primed for big, big things and the mood is the franchise will go a different route and embrace girl power and move with the times," spills an insider.

As The National ENQUIRER has reported, Matthew, 54, has yet to sign a deal to star in a Yellowstone spinoff and sources say bosses are still dragging their feet over his eye-popping $2.5 million per episode fee.
