A source told the New York Post newspaper: "Jenna had a bunch of meetings and things planned for Fashion Week, including meetings for her own line, but she's postponed everything."

"She's completely thrilled, this is something she's wanted for a very long time."

Jenna has made no secret of her desire to have children with Tito, but insists she does not want to marry the sportsman. Speaking earlier this year, she said: "I think I'm going to stay unmarried, and just go for the babies! We're trying for a baby, so hopefully in the next couple of months I could be pregnant."

The 34-year-old beauty - who is widely considered to be the "Queen of Porn" - was pregnant when she was married to Jay Grdina, but miscarried. The couple divorced in 2006.
