Showing their support, expectant parents Nicole Richie and Joel Madden attended a private screening of Playground last Monday evening in Los Angeles.

The documentary, which premiered earlier this year at the Tribeca Film Festival, focuses on “the child sex trade in the United States and discrepancies in laws and the perception of the exploitation of foreign and U.S. children.”

Nicole, 27, and Joel, 30, expect their second child in late August.
