According to TMZ Sports, Vonn seemingly confirmed that she and Subban are a couple by posting a photo of them together on her Instagram story with a yellow heart emoji.
Vonn and Subban have been a rumored item in recent months; they were spotted together at a Boston Red Sox game and Boston Celtics game in May.
Vonn also attended one of Subban's playoff games, according to TMZ.
The 33-year-old Vonn is a three-time Olympic medalist and a four-time winner of the World Cup overall championship.
Vonn is the all-time record holder in World Cup race wins among women with 82.
She previously dated golfer Tiger Woods from 2012-2015.
He enjoyed one of the best seasons of his career in 2017-18, with 16 goals and 43 assists for 59 points.
Although the Winnipeg Jets ended the Preds' hopes of returning to the Stanley Cup Final in the second round of the playoffs, the exit allowed Subban to hit the town with Vonn on Wednesday.
