Adult film star and actress Jenna Jameson is pregnant, she confirmed to Us Weekly.

"Yes, I can confirm I'm pregnant. It's still early, so I'm being cautious. I'm resting as much as possible," she said. "I'm so happy!"

The baby will be the first for the 34-year-old and her boyfriend of two years, ultimate fighter Tito Ortiz, 33.

Previously married to fellow porn star Brad Armstrong and adult film studio owner Jay Grdina, Jameson had long wanted to start a family. She suffered a miscarriage in 2004 after being diagnosed with skin cancer and was unsuccessful with in vitro fertilization. - Joyce Eng
