Vonn, who retired in February with a female record 82 World Cup wins, and Subban, a New Jersey Devils defenseman, have dated for more than one year.
Vonn was previously married to fellow Olympic skier Thomas Vonn in 2007. They announced divorce plans in late 2011.
Vonn reportedly grimaced when asked in 2013 if she would get married again.
“No, thanks!” she said, according to Vogue then. “I am definitely not getting married. To anyone.”
After her divorce, Vonn dated Tiger Woods and NFL assistant coach Kenan Smith before dating Subban, going public in June 2018.
“Right off the bat, I knew he was different,” Vonn said, according to a Vogue magazine announcement of the engagement. “But I’d been married before, so I was pretty hesitant to let myself think that I could find someone that I would want to be married to again. After a few months of dating, I knew he was the one I wanted to be with, though.”
Subban, 30, also owns an Olympic gold medal playing for Canada in Sochi.
“Lindsey’s the best thing that’s ever happened to me,” Subban said, according to Vogue. “There are people in life that deserve to be with good people. They have that person who takes care of them and makes them smile, and she deserves to be with someone who loves her more than anything else in the world, and I do.”
Vonn and Subban would become one of the most prominent married Olympic champion couples, joining the likes of tennis players Andre Agassi and Steffi Graf and gymnasts Nadia Comaneci and Bart Conner.
