Nicole Kidman and Keith Urban live a pretty private life, so we love seeing their cute kids whenever we can!

Since the family lives in Nashville, daughters Sunday Rose and Faith aren't photographed as some other celebrity kids (See: Suri, Flynn, any of the Kardashians).

But the Urban-Kidman clan was spotted at LAX earlier today, and we can't believe how big Sunday (right) is now. She looks just like her daddy!

The two girls were seen wearing matching green dresses, shoes and socks as they left the airport, mamma Kidman carrying Faith as they passed photographers.

The sighting comes after Nicole's other kids -- son Connor and daughter Isabella -- celebrated Bella's 18th birthday with ex-husband Tom Cruise in Florida. It's unclear how close they still are to Nic.
