Justin Timberlake's Mother wants him to impregnate Jessica Biel.

I have a feeling the last thing Justin wants to do is think of Mommy while having sex with Jess.....

Fox: If Jessica Biel wants to hold off on having children, she might want to steer clear of boyfriend Justin Timberlake's mother.
An eyewitness tells FOXNews.com that Timberlake's mother, Lynn Harless, was outside a party saying she doesn't want to be an "old grandmother" and is pushing her son to get on with procreating, already.
Harless said she was 20 when she had Justin, and that being a young mother is ideal because you have "so much more energy," and added that Justin's career was so successful, he had the opportunity to focus now on "other things."
Like children.
