Rare View Into Katherine Heigl's Family Life with Her Children

In a recent snapshot Katherine Heigl posted online, her children have all reached adulthood.

The Grey's Anatomy star's most recent Instagram photo is particularly noteworthy because she rarely lets the world into glimpses of her private life with her family.

Adalaide, a 10-year-old, and Katherine can be seen smiling and posing for the snapshot 

Joshua, the actress' 5-year-old son, is also shown in the photo.

Katherine captioned the photo with just a red heart emoji to express her love without saying a word.

Adalaide, Joshua, and Naleigh,13, are Katherine and Josh Kelley's three children.

After Adalaide was born in Louisiana in2012, her parents adopted her.

Naleigh, who was born in South Korea, was adopted by Katherine and Josh three years ago when she was just nine months old.
