It’s his first major win since the 2008 U.S. Open, and many of his friends and family were there to celebrate with him, including his girlfriend Erica Herman.

Want to learn more about her? Here are a few fast facts.

Herman worked at Woods’ restaurant.

She is the former general manager of Woods' Florida  restaurant, The Woods Jupiter, which opened in 2015. She has not worked at the restaurant since February, according to TMZ.

She began publicly dating Woods in 2017.

Herman, 33, has been linked romantically to Woods, 43, since last fall when she followed the golfer during the President's Cup when he served as captain's assistant.

In 2018, she went viral after kissing Woods after the PGA Championship.

During last year’s PGA Championship, she greeted Woods with a smooch. The two briefly kissed and exchanged words.

The moment went viral and left some wondering about the mystery woman for the first time.

She has attended many of Woods’ games.

In July 2018, she watched Woods during the Open Championship alongside his children, Sam and Charlie.

She also cheered him on at the Hero World Challenge, the Tour Championship and the Ryder Cup.

Herman has also joined Woods at several other events. 

The duo has been seen together on dates. They also attended the Wimbledon tournament last summer to watch Serena Williams and the World Series game last October.

Herman is Woods’ third known girlfriend since his divorce from Erin Nordegren.

Woods divorced Nordegren in 2010 after a revelation of extra-marital affairs. He famously dated Olympic skier Lindsey Vonn starting in 2012. They split in 2015. He dated Kristin Smith from 2015-2017.
