Katherine Heigl and her husband Josh Kelley have adopted another baby.

The Knocked Up actress and her musician husband adopted three-year-old daughter Naleigh from South Korea in 2009 and ET Canada has reported they have now adopted another baby girl.

The couple's representative Jill Fritzo told People: "Yes they have adopted a baby. No further details are available at this time."

Katherine - who has an adopted sister - revealed earlier this year that she and Josh, 32, would like to do it again.

The 33-year-old actress said: "Josh and I started talking about it before we were even engaged.

"My sister Meg is Korean, and my parents adopted her three years before I was born. I wanted my own family to resemble the one I came from, so I always knew I wanted to adopt from Korea.

"We have talked about having biological children as well, but we decided to adopt first. I just wanted to be a mom.

"So however we do that, it's fine with me. I'd like to adopt again."
