Jason Biggs and wife Jenny Mollen are expecting a baby.

The "American Pie" star shared the news during an appearance Wednesday on "Chelsea Lately."

"Her breasts look really engorged," host Chelsea Handler remarked of a recent photo of Mollen.

"Her breasts are very big these days," Biggs replied. "Would you like to know why?"

After a pause, he added, "Cause I put a baby in her belly!" The actor then pointed to his crotch and joked, "It works!"

Mollen later confirmed the news herself, sharing a sonogram photo on Instagram. "My new assistant is so [expletive] lazy!" she wrote.

This is the first child for Mollen and Biggs, who currently stars on Netflix's "Orange is the New Black."
