Outside of Keough’s career, she married stuntman Ben Smith-Petersen in 2015. The couple met while filming Mad Max: Fury Road back in 2012. Keough and Smith-Petersen welcomed their daughter, Tupelo Storm Smith-Petersen, in 2022.

“It’s funny because we picked her name before the Elvis movie,” Keough said in an August 2023 story for Vanity Fair. “I was like, ‘This is great because it’s not really a well-known word or name in relation to my family—it’s not like Memphis or something.”
