Lindsey Vonn popped the question to New Jersey Devils star P.K. Subban.
Vonn linked a picture of herself and Subban with the ring, with the couple wearing matching striped pajamas in front of a Christmas tree with three dogs in the foreground. She also posted a close-up of Subban flashing the ring, with the words "drip drip" and a blue teardrop.
Vonn also said on social media in August that they were engaged.
The 35-year-old Vonn recently retired from a skiing career that included three Olympic medals, four overall World Cup titles and 82 World Cup race victories, a record for a woman.
The 30-year-old Subban won the 2013 Norris Trophy with Montreal as the NHL's top defenseman. He was traded in June to New Jersey from Nashville.
Vonn had a high-profile relationship with golfer Tiger Woods. She previously was married to former ski racer Thomas Vonn, and kept his last name after they separated.
