Sarah Michelle Gellar was gobsmacked when recently asked to look at a stranger's breasts.

According to The Sun's Bizzare column, the Buffy star was confronted by a busty lady at her Los Angeles gym.

"This girl was topless in the changing room and, out of the blue, asked me, 'What do you think of these? I've just had my boobs done.' I said, 'They look really nice', even though I hate fake breasts."

Sarah added, "If a tidal wave hits L.A., just grab a fake boob for safety."
