Jessica Biel is reportedly keen on "building a family".

The 30-year-old actress wed husband Justin Timberlake, 31, earlier this month.

Although Jessica is enjoying newlywed bliss, she is eager to plunge into having children.

"Jessica's hitched and now she's ready for a baby, as soon as possible!" a source told Radar Online.

"After her dream Italian wedding, Jessica told Justin that she is ready to have his children and she wants him to start thinking about building a family too.

"Jessica has been gearing up for motherhood for a while, but being the traditionalist she is, wanted to wait till after she got married."

Jessica knows exactly how many tykes she wants running around her house.

She is very intentional about how she and Justin will reproduce.

"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," the source said.

"And it couldn't be a more perfect time to start making babies they both have a break in their schedules to put in the ground work!"

Justin and Jessica began dating in 2007.

It is the first marriage for both stars.
