The twins boom shows no signs of slowing! In a MySpace entry today, Jenna Jameson — who confirmed her pregnancy last month — announced that at her second ultrasound she was "greeted by two big healthy babies with pounding hearts." Writes Jenna,

Jenna’s boyfriend, ultimate fighter Tito Ortiz, is over the moon at the news of twins. "Tito is happier than I have ever seen him, it is so fulfilling to see him so proud," Jenna says. The 34-year-old actress and former adult film star also shared that she was moved to tears when Tito told her after their ultrasound "I’m the luckiest man on earth… thank you for having my babies." It hasn’t all been coming up roses for Jenna, however. She shared that she’s been "incredibly fatigued and nauseous," which has led her to be on self-imposed bedrest. When she can bring herself to eat — having gained seven pounds so far and "planning on a lot more" — Jenna says she craves "fruit by the gallon" and "cereal at 3 a.m."
