Katherine Heigyl found it hard to bond with her adopted daughter Naleigh.

 Actress Katherine Heigl and her singer husband Josh Kelley have adopted a second child.

The couple adopted baby daughter Naleigh from South Korea in 2009 when she was 10 months old, and now the star has become a mum once again.

A representative for Heigl confirms to ET Canada that she and Kelley have taken in another girl, although further details were unavailable as WENN went to press.

Heigl recently spoke of the initial difficulties she had bonding with Naleigh, telling German newspaper Bild am Sonntag that it wasn't easy.

"People are always talking about the strong bond between mother and daughter, this magical connection - but we didn't have that," the 33-year-old said.

She revealed that the first few weeks when she got Naleigh home were "the hardest in my life".

"I fought incredibly hard for my daughter to accept me as mother. Her rejection almost broke my heart."

The star said that she initially focused on her work as a way to cope but that made the "already difficult process of getting closer take even longer. I immediately cut back on work."

Heigl hinted at another adoption back in January.

"We have talked about having biological children as well, but we decided to adopt first. I'd like to adopt again," she told People magazine.
