Welcome to the family business, Seraphina Rose Affleck!

The newborn, just shy of two months old, hit work with mom Jennifer Garner in Los Angeles yesterday, where Mrs. Ben Affleck finished reshoots for her film Invention of Lying.

“Violet was at school and Jennifer hung out with the baby in her trailer,” a source tells Celebuzz.

Invention, costarring Ricky Gervais, Jason Bateman and Tina Fey, wrapped initial production in June of 2008—when Garner sported nowhere near the baby bump she was carrying around before her January 6 delivery.

Celebuzz can confirm that reshoot costumes for the actress are Size 8, and that “Jennifer looks radiant.”

Months of pregnancy speculation followed the star couple last year, as both remained mum on a potential sibling for three-year-old Violet, eventually confirming last August.

Invention is currently slated for a 2010 release.
