Ronda Rousey refused to shave her head for 'Mile 22' because she has an endorsement deal with a hair-care firm.
The 31-year-old star has revealed that director Peter Berg was eager for her to shave off her glamorous blonde locks ahead of filming the new movie, but Ronda insisted she wouldn't because she has a deal with Pantene.
She told Collider: "He was like, 'I want your head shaved, gone.' And I was like, 'Pete, I've got a Pantene deal - you can't shave my head.' So on the first day of shooting, there's fire everywhere and I'm like, 'This is just because he wanted my head bald and he's going to try and burn all of my hair off today.'"
Meanwhile, Ronda - who joined the WWE earlier this year - recently insisted that wrestling is tougher than acting.
