Here is her announcement:

Jenna told the audience, "I really want to be honest for a second. I want everyone to know that I know that US Weekly came out and said I was retiring and that I was done with the industry. I had to come back and talk about the fact that I wasn’t done. Clubjenna is one of the biggest forces in this industry by far and away. But, honesty is key. I will never ever every spread my legs again in this industry ever."

Jenna with her husband Jay Grdina founded the porn based entertainment company ClubJenna in 2000. This comapny is now a major producer  of hardcore porn films as part of Playboy.

Jenna stated that she will focus on her successful web business ventures. She also is independantly wealthy having sold Clubjenna.com to Playboy Enterprises for undisclosed millions in June of 2006. 

I wonder what took her so long!
