The `Total Recall` actress only tied the knot with Justin Timberlake on 19.10.12 but she is keen to start a family with the singer-and-actor sooner rather than later.
A source told RadarOnline.com: "Jessica`s hitched and now she`s ready for a baby, as soon as possible!
"After her dream Italian wedding, Jessica told Justin she is ready to have his children and she wants him to start thinking about building a family too."
Jessica has apparently been thinking of becoming a mother for some time but she wanted to wait until she was married before getting pregnant because she believes in traditional family values.
The source added: "Jessica has been gearing up for motherhood for a while, but being the traditionalist she is, wanted to wait until after she got married.
"She is planning for two kids, ideally a boy and a girl, because she grew up with a younger brother herself and believes it`s healthy to have siblings."
Jessica and Justin, 31, tied the knot in a top secret ceremony at the Borgo Egnazia resort in Puglia, Southern Italy, attended by family and close friends, including Andy Samberg, Jimmy Fallon and Beverley Mitchell.
The couple said in a statement: "It`s great to be married, the ceremony was beautiful and it was so special to be surrounded by our family and friends."
