The actress said she was pleased to receive the accolade seven months after giving birth to daughter Nuala.
"I don't know exactly what it means, but being 42 and having just had a baby, I think I'll take it," the actress said.
Berry, who thrilled James Bond fans when she emerged from the waves wearing an orange bikini in Die Another Day, joked: "I've been in the business for more than 20 years, and you decide now, at this particular time, that I'm the sexiest woman alive? Come on. I mean, you couldn't go with the Bond girl year?"
