In his upcoming movie "8 Mile," opening in November, rapper Eminem plays a character loosely based on himself: a struggling, aspiring rapper trying to make it out of Detroit in the mid-'90s. Looking at his real life today, Eminem (real name: Marshall Mathers III), 29, tells MTV that fatherhood is the most important thing to him. "I'm a father before anything," he says. "I'm a father before I pick up the mic. I'm a father before I'm Eminem. Of course I'm not the perfect parent. There may be things I'm doing wrong and I'll find out in 10, 15 years, but right now I'm doing the best job I can and that's all I can do." As for having more children, "No more kids," says the rapper. "I'm good with Hailie. I'll spoil her and give her everything I never had. I have other family members that I take care of and want to take care of, but as far as kids, I'm cool. No more, one is enough." And for now, daughter Hailie, 6, is also the only significant female in his life. "I'm not looking for a new woman. I'm cool being single -- not to say I don't get down (laughing). But as far as a relationship or getting married again, I'm cool, man. I learned my lesson and I've seen what it is and what it can and can't be and I feel like I've learned enough from my first mistake. Let that be the last one and keep moving forward."
