Ronda Rousey's star power continues to grow even when she's not defending her UFC women's bantamweight championship. Her first featured film role opened two weeks ago in "The Expendables 3," and she has a couple high-profile roles on the way in Fast & Furious 7 and the new Entourage movie in 2015.

To add to her charm, Expendables director Patrick Hughes disclosed a funny story from Rousey's first day on set. Apparently she was a bit nervous before shooting her first scene, so to calm down she sparred with Hughes and the end result was a broken rib for the director.

"I remember the first thing we shot with Ronda, I actually got beaten up," Hughes said in an interview with HitFix. "Ronda's first time ever on camera was the scene with Sly at a bar, and she's really super-nervous. I went up and said, 'Well, what do you do before a big fight?' And she says, 'I like to spar in my room. I get that nervous energy out.' And I said, 'So you need to hit something? Let's find something to hit.' And she said, 'But I want to hit you.'

"She was like, 'Put your arms up.' And I'm thinking, 'Ronda's just going to do this,'" Hughes continued. "Put my hands up, and she goes WHAM! Next day, I was getting dressed and my kids were there at the time, my 7-year-old daughter said, 'What's that?' And I had this huge black mark. I had a broken rib. And I said, 'I got beaten up by an actress.'"

Rousey admits to giving Hughes a punch, but disputes his claim that she broke his rib. "He didn't have broken rib! I didn't hit anything hard," she said.

Rousey said she was initially intimidated being paired up with big-name actors like Sylvester Stallone, Arnold Schwarzenegger and Wesley Snipes. But once she got over her first-day jitters she was able to fit right in.

"Everyone really, I felt, went out of their way to make me feel comfortable, and I couldn't have asked for a better first project to be on," she said. "And I've always been the one shaking it down with all the guys anyway. I would have felt more uncomfortable if I were in Sex and the City 4. So I'm really happy."
