Michelle Rodriguez's latest interview might explain her very famous flings.
"I have absolutely nothing consistent in my life," she says. " ... I'm a lone wolf. I run by myself on most things. I've got lots of really great friends, but the thought of being in a long-lasting relationship? Psh, I couldn't last more than six months with somebody, let alone have a father figure around for a kid."
She also feels she has much more to accomplish in Hollywood before settling down.
"I wouldn't want to sacrifice the last years that I have of being youthful in this business to have kids," she says bluntly. "I haven't done what I came here to do. I'm just kind of fiddling around. I haven't even been born yet. I've been part of really big things that are amazing, but I haven't taken on that responsibility yet. So I don't want to sell myself short by having a kid and then regret not doing what I set out to do."
Though Michelle's love life certainly kept everyone on their toes last year. Michelle and 27-year-old Neighbors star Zac Efron flaunted their PDA in Ibiza but split in August after only two months together, and she split with 22-year-old model Cara Delevigne in May after similar PDA-packed sightings. The two were reportedly together for four months.
"I've always been and will always be very private about my personal life," she says about all the interest on her relationships. "If anything ever goes public, it is by default, because I happened to be in a place where I was being watched. But for the most part, I honestly don't care what people think. I never have. If I did, I'd probably present myself a little more carefully."
Michelle's unguarded persona clearly extends to one of her most beloved roles -- the tough-talking Letty in the Fast & Furious franchise -- whom she lovingly calls a "whore." It turns out Michelle actually got producers to change the script, which originally called for her character to be with both Vin Diesel's character Dominic and Paul Walker's character Brian.
"Yeah, she's a whore," she laughs. "But, you know what it is? People don't like talking about it, but if you're Spanish, you feel a weight. I don't have the freedom to just do anything, because I have the political weight of having this last name and my heritage. So when I looked at Letty, I told them, 'You can't do the stereotype thing. Either you don't make her slut -- not make her a character that gets with both [Vin Diesel's character and Paul Walker's] and you respect her, or you're going to lose me."
And she wasn't afraid of the consequences.
"And you can sue me and do whatever because I'm from Jersey City, what the f*ck do I give a f*ck?," she explains. "I'll go back to where I came from. Whoop-de-do. You're not hurting me none -- it's not like I'm losing millions. Vin [Diesel] protected me. He was like, 'Wait a minute, I don't want a slut for a girlfriend! That makes me look bad.'"
The latest installment of the super-successful Fast & Furious franchise hits theaters on April 3.
ET caught up with the late Paul Walker's father in November, Paul Walker III, when he talked about his two sons Caleb and Cody Walker stepping in as body doubles for Paul.
