Jenna Jameson says "500 sit ups a day" made giving birth easy. The former adult movie star - who welcomed twins Jesse Jameson and Journey Jette into the world on March 15 - boasts her strong stomach muscles aided the fast delivery.
She wrote on her MySpace blog: "I was blessed with a very easy labor, it lasted about 2 hours. When it came to pushing them out, I truly believe the 500 sit ups a day paid off. I was able to push my 5 pound Jesse out in 5 pushes. Journey who was 4lb 11oz was out in 3 pushes."
Jenna was forced to spend two months in hospital on bed rest prior to the birth, but insists the experience hasn't put her and her partner, mixed martial arts fighter Tito Ortiz, off having more children.
She said: "I loved the whole process of being pregnant and I hope to have another baby someday.... but in the meantime, I'm having a blast with my two little monsters! By the way, Jesse looks like me and Journey looks like Tito! I feel like the luckiest girl ever!!!!!!"
