Katherine and her husband Josh Kelley are already proud parents to their three-year-old adopted daughter, Naleigh, but it has now been confirmed that they have adopted another child.

A spokesperson said that the pair have "adopted a baby", with reports suggesting that she's a little girl from Louisiana.

Heigl and Kelley adopted their daughter, Nancy Leigh from South Korea in 2009 and Katherine herself has an adopted sister, also from South Korea.
