Heidi Klum Beverly Hills Leni Lou Ballet

Supermodel Heidi Klum picked up daughters Leni and Lou at ballet class in Beverly Hills on Saturday, where Leni looked like a prima ballerina ... until she let out a shriek!

Maybe Leni was screaming about her mom's new status on the annual "Most Dangerous Celebs" list released by McAfee Security. Klum replaced Cameron Diaz as the celebrity most likely to lead Internet users to a virus if they search for her name -- scary!

We still love you, Heidi ... and you too, Leni.
