Drew Barrymore is about to become a mom, and no one is more excited for her than best friend Cameron Diaz! The famous friend threw the mom-to-be a baby shower bash on August 4.

The family-friendly event was attended by both male and female guests (including dad-to-be Will Kopelman), as well as kids! On the property owned by Drew Barrymore and her new husband was a bouncy house for little ones to have a blast in.

Also in attendance among the approximately 50 guests? Her and Cameron Diaz’s Charlie’s Angels costar Lucy Lui!
