Edgerton gave a shout-out to Australia's Fred Hollows Foundation, which focuses on treating and preventing blindness and other vision problems, while Negga offered her continued support to the American Civil Liberties Union (ACLU), which works to defend and preserve individuals' rights and civil liberties.
ET teamed up with Moët & Chandon for Toast for a Cause at the awards show, where Moët generously donated $1,000 to stars' charities of choice.
Negga and Edgerton's latest film, Loving, has special ties to the ACLU, recently announcing the "We Stand for Love" online auction hosted by Charitybuzz, which will donate the proceeds of bidding on events and experiences related to the movie to the ACLU of Southern California.
The ACLU represented the couple at the center of the Golden Globe-nominated film, Richard and Mildred Loving, in the 1967 landmark civil rights case, Loving v. Virginia, which went all the way to the United States Supreme Court and reaffirmed the foundation of the right to marry.
Loving has in turn supported the organization, with Negga, Edgerton and writer/director Jeff Nichols attending a Los Angeles screening of the film, co-hosted with the ACLU of Southern California, last week.
