Justin Timberlake and Jessica Biel share ''strong family values''.

The 'Total Recall' actress, who married the 'SexyBack' hitmaker in Italy in 2012, is reportedly expecting their first child and their friends have no doubt they will be great parents.

A source said: ''Justin will be a natural dad. And Jessica's always wanted to be a mom. That's why they are together. They share strong family values.''

The 32-year-old actress recently hid her growing baby bump at their Halloween party in Los Angeles with her costume and although she has yet to comment on rumours she is pregnant, the actress is already well into her second trimester.

The insider told Us Weekly magazine: ''Jess is 18 weeks pregnant.''

Meanwhile, Justin, 32, is planning to cut back on his busy schedule once their tot is born next spring.

The insider said: ''He's been touring too much.''

The singer's Memphis-based grandmother, Sadie Bomar, previously revealed he couldn't wait to have children.

Shortly after he got married, she said: ''Last time Justin was here he said, 'Granny, I want a family.' He sees his cousins with kids and he wants that too.''
