Just call her Heidi Samuel!

A Los Angeles court commissioner officially approved supermodel Heidi Klum's request to adopt husband Seal's last name Friday.

There is no word yet on if she will adopt the surname professionally.

The Project Runway hostess, 36, filed paperwork early last month in court to legally change her name, citing 'marriage' as the reason for the change.

Her decision to take Seal's last name (his full name is Seal Henry Olusegun Olumide Adeola Samuel) comes four years after they wed.

Klum gave birth to the couple's third child together, daughter Lou, five weeks ago. She and Seal have two sons, Henry, 3, and Johan, 2, and Seal, 46, is the adoptive father of Klum's daughter Leni, 5.
