Vonn's rep released this statement:
Lindsey is currently in the midst of the World Cup season in Europe. Her focus is solely on competing and on defending her titles and thus she will not participate in any speculation surrounding her personal life at this time.
Woods' team has yet to respond.
Three years have passed since Woods' extramarital activities ended his marriage and shattered his public persona as a hard-working athlete and family man. Vonn divorced her husband, Thomas, in 2010.
