Olympic Gold Medalist Lindsey Vonn is a huge fan of professional golfer boyfriend Tiger Woods, calling her beau of seven months the “Greatest of all time.”

Us Weekly reports that Vonn took to Twitter to praise Woods writing, “So proud!!!! #79 #GOAT.” As Us Weekly notes, GOAT is the acronym for “Greatest of all time.”

Rumors that the Olympic skier and pro golfer were an item surfaced earlier this year. Woods and Vonn confirmed their relationship just months later writing, “I guess it wasn't a well-kept secret but yes, I am dating Tiger Woods. Our relationship evolved from a friendship into something more over these past few months and it has made me very happy." Vonn, 28, has stood by her man during a majority of his competitions as of late.

Vonn has since been open about her relationship telling Vogue last month that her relationship is “amazing…"Life changes very quickly, in a very positive way, if you let it."
