The "Big Miracle" star's big news comes just 13 months after the birth of her first child, Olive.
The news came after Barrymore was spotted in a baby bump-concealing gown at the LACMA Art+Film Gala Saturday. However, it was only confirmed Monday.
The 38-year-old married Kopelman, an artist, in June 2012.
Barrymore had recently admitted that she wanted to increase her brood.
