Katherine Heigl boots blonde hat daughter adopted airport lax

Katherine Heigl is a momma on a mission!

The now-blonde actress held on tight to her daughter Naleigh while quickly entering LAX ... preparing to catch an outbound flight.

In addition to caring for her adorable little girl, Katherine has been busy lending her starpower to helping control the pet population. The actress recently donated $1 million to help no-cost spay and neuter clinics in LA.

Grey's Anatomy is no longer on her agenda, but Josh Kelley's wife is certainly keeping busy!
