JENNA JAMESON - JAMESON'S BABY PROBLEMS

Porn queen JENNA JAMESON is having problems conceiving her first child with her husband and co-star JAY GRDINA.

The buxom DREAM QUEST actress and Grdina - whose stage name is JUSTIN STERLING - have been trying for a baby for months. The blonde has undergone a series of fertility tests at a hospital and doctors have told her nothing's wrong.

Jameson tells ROLLING STONE magazine, "I really, really want it to happen. I'm trying to think positive, but sometimes I can't."

She has vowed to quit her mega-successful porn career once she becomes pregnant.

She explains, "I want to be able to say, 'Yes, Mommy was once a porn star, but when you came along, Mommy was no longer a porn star.'"
