The announcement was reported exclusively on celebrity gossip blogger Perez Hilton’s website.
After debunking earlier rumors of her pregnancy, Jameson informed Perez that she was indeed pregnant.
"Funny enough, that story was fake, but I just found out I am pregnant," Perez quoted her as saying.
Quoting sources, Perez also reports Jameson and Ortiz have recently bought a beachfront home in Los Angeles. Jameson' ex-husband, Jay Grdina, told XBIZ he was excited for the couple.
"I know Jenna wanted to have children more than anything in life and I feel extremely happy for her," Grdina said. "She will be a great mom. Watch out world, here comes another Jenna."
