The couple took a page from Katy Perry's and Orlando Bloom's book by tasking their chosen charities to break their baby news.

Seyfried and Sadoski wed in March 2017 and, along with their newborn son, share a 3-year-old daughter, Nina.

The \"Mean Girls\" alum also gave fans an aww-worthy moment whens he shared an adorable snap to Instagram Stories on Monday showing her two children gently holding hands.

Seyfried, 34, and Sadoski, 44, are board members of INARA and ambassadors to War Child USA. They had not announced their second pregnancy publicly.
