Thomas Vonn confirmed the information in an email to The Associated Press on Thursday night. The couple announced their separation more than a year ago.
In the email, he said: "I wish Lindsey all the best in her new life. I hope she finds the happiness that she's looking for — that's all I've ever wanted for her."
The news was first reported by TMZ.com.
Lindsey Vonn left the circuit in mid-December for three weeks to fully recover from an intestinal illness, but recently returned to the slopes. The four-time overall World Cup champion plans to ski in downhill and super-G races this weekend in St. Anton, Austria.
