Supporting her man despite his well known history of infidelity, Lindsey Vonn congratulated Tiger Woods via her Twitter account on Sunday (August 4).

Following the athlete's win at the WGC-Bridgestone Invitational, the medal-winning Olympian tweeted, "So proud!!!! #79 #GOAT," referring to his 79th PGA victory and the acronym "Greatest of All Time."

After confirming their relationship five months ago, the 28-year-old skier described their romance as "amazing" in Vogue's August issue.

Though they may be getting serious, don't expect to see Lindsey in a white dress anytime soon, as she told the magazine, "No, thanks! I am definitely not getting married. To anyone." Check out the video of Tiger picking up his son Charlie after his win this past weekend.
