'Yellowstone' Star Hassie Harrison Flashes Rock, Confirms Ryan Bingham Marriage

Yellowstone’s Hassie Harrison and Ryan Bingham are deep in the throes of newlywed bliss … with the actress now proudly taking her wedding ring out for a spin.

Video footage shows Hassie flashing her rock at the Wynn Hotel in Vegas … at a fun-fueled after-party for Ryan following his performance at the city’s Virgin Hotel Thursday.

The newlyweds are filmed singing one of Ryan’s new, unreleased songs … which sources at the bash tell TMZ he wrote for her and requested she come up on stage to sing it together.

The ring is a little hard to see at first — with the pair gazing into each other’s eyes and sharing a passionate smooch — but as the blushing actress heads off stage with her hands up to her face, the sparkler is visible.

For added measure … a source tells TMZ that friends and family were heard referring to Hassie as Ryan’s “wife” … so for any doubters, it looks like they’re well and truly hitched!

The sighting comes days after Ryan first prompted marital speculation by sharing two snaps wearing a wedding band — with sources telling TMZ they married in early Oct in Dallas — Hassie’s hometown.

Ryan and Hassie’s relationship has been a whirlwind … going IG official in April, purchasing a Topanga Canyon ranch over the summer, and exchanging vows a few months later.
