The adult industry icon gave birth yesterday to twin boys, fathered by her current beau, Ultimate Fighting Champion slugger Tito Ortiz. They've been together for two years.
The twins arrived Monday morning, according to USMagazine.com, which reported that Jameson was in good health.
Jameson and Ortiz remain unmarried, a state that the former adult performer has no plans to change, despite her self-professed Catholicism.
"I think I'm going to stay unmarried and just go for the babies," Jameson said. "I'm following in Angelina [Jolie]'s footsteps."
Jameson became pregnant back in 2004, but soon after discovered that she had skin cancer. She miscarried while undergoing cancer treatment.
The Club Jenna co-founder publicized her most recent pregnancy happily and often, dishing to websites and newspapers about the story and occasionally invoking her religious feelings about the affair.
"I truly feel like finally the time is right and god has blessed me," she wrote on her MySpace blog, where she also posted pictures of her expanding belly. "I have never felt more like a woman, or more alive."
In February, Jameson unveiled a new perfume line called "Heartbreaker," which is available at HeartbreakerByJenna.com.
