Heidi Klum is ready to become a mom again - the supermodel has checked into Cedars-Sinai Medical Center in Los Angeles as she prepares to give birth to her fourth child.

The German star's mother was spotted dropping Klum's three kids off at school in Los Angeles on Wednesday morning before picking up healthy provisions for her expectant daughter.

Klum's mother, Erna, and a bodyguard went shopping at a Hollywood wholefood market and then dropped off the goodies at the hospital, where the supermodel reportedly checked in overnight.

Klum's publicist could not be reached as WENN went to press.
