Congratulations are in order for Jason Biggs and Jenny Mollen.

The American Pie star, 38, and the Life Happens actress, 37, are expecting their second child, they announced via Instagram.

“This is how I told my son babies are made #numbertwo,” the actress-author captioned an image of a couple using a NoseFrida snot sucker.

The newborn will join 3-year-old big brother Sid.

In February, the Orange Is the New Black star shared birthday greetings for their preschooler.

The couple – who were wed in April 2008 – welcomed their first child on Feb. 15, 2014.

Congratulations to the Mollen-Biggs family!

This is how I told my son babies are made. #numbertwo #nosefrida @fridababy #teetsreincarnated
