Hearst Magazines’s CosmoGirl is being shut down, reports WWD.

The teenage spin-off of Cosmopolitan, which targeted teenage girls and featured fashion and celebrities, will finish off with its December issue. (Scarlett Johansson was just featured on its November 2008 cover.)

CosmoGirl’s subscriber base will be folded into fellow Hearst title Seventeen.

Editor in chief Susan Schulz will be “staying on at Hearst to work on special projects.”

All of these poor teen titles!
