She was later pictured on the red carpet with her arm around Tatum, 35.
The brave blonde, who got her start as a stuntwoman in Xena: Warrior Princess at the age of 17, turned actress for The Hateful Eight.
When informed she would need to pick up the skill of driving a stagecoach, she was quick to master the art.
"She [Six Horse Judy] is actually quite cute, quite sweet, but she drives a six horse coach - a stagecoach with six horses," Bell told The Independent.
"She is tough because that is quite hard."
It's a smaller part, which didn't require the risky moves Bell pulled in Tarantino's Death Proof or as a stunt double in Kill Bill or Catwoman.
She won't however be featuring in any scenes of one-on-one combat.
"It's purely an acting role ... It's a smaller role but she is a very fun character."
