"My motivation is taking care of my family and having fun and meeting all my fans," the 39-year-old told TMZ Monday.
Jameson's return to the industry she swore she had left behind comes at a time when the popular porn star is in need of some financial help.
She recently lost her Hollywood Hills home to foreclosure, got a DUI last year after crashing her car into a light pole, and is separated from Tito Ortiz, who claims she has an addiction to Oxycontin.
In an interview with "Oprah: Where Are They Now?," Jameson cited her family as the reason she initially left the adult industry.
"I made a promise to my children when they were in my tummy that there is no way I could ever, ever, ever go back," she said at the time.
Jameson's latest foray back into porn comes in the way of a webcast in which she strips and performs sex acts online in exchange for tips.
At her peak, Jameson's Internet pornography company, ClubJenna, hit revenues of $30 million in 2005 and with her sex toy line and videos, was recently worth a reported $10 million.
