"Thank you, August for leaving a legacy to actors of color that we can relish for the rest of our life," Davis said, while also thanking her fellow nominees Carey Mulligan, Amy Adams, Vanessa Kirby and Frances McDormand.

"I couldn't have been in better company, thank you so much," she said of her fellow nominees.

This win marks the fifth SAG Award win for Davis, who most recently won the supporting actress trophy in 2017 for Fences. She went on to win Oscar gold that year.

Davis has been critically praised for her performance as the legendary Ma Rainey.

She and Boseman star together as musicians at odds, as Boseman's Levee wants to break free from just being part of Ma Rainey's band.

The actress recently extended her own record as the most-nominated Black actress ever at the Oscars when she was nominated for Best Actress last month.

The 27th annual Screen Actors Guild Awards are airing Sunday, April 4 on TNT and TBS.
