Sarah Michelle Gellar Remembers Robin Williams on Second Anniversary of His Death

Sarah Michelle Gellar flashes a smile in a star-printed dress as she goes on a shopping trip on Thursday (August 11) in Brentwood, Calif.

Earlier this week, the 39-year-old actress shared a photo on her Instagram account showing her support of her friend Shannen Doherty, who is fighting cancer.

The same morning of her shopping trip, Sarah took to Instagram again to post another touching message, this time to her friend Robin Williams, who passed away two years ago.

Sarah and Robin worked together on the sitcom The Crazy Ones, one of Robin‘s final projects.

“‘Time is the best teacher, but unfortunately, it kills all of its students’ #robinwilliams,” Sarah captioned the sweet pic (below).
