The Supermodel Formerly Known as Heidi Klum

TMZ has learned Heidi Klum was officially docked a few precious sexy points today -- because she just had her last name legally changed from "Klum" to "Samuel."

The Victoria's Secret supermodel filed papers early last month asking permission to take on the last name of her husband, Seal Henry Olusegun Olumide Adelo Samuel -- she was finally given the okay today.

It could have been worse ... she could have changed her name to Heidi Olusegun.
