Josh Kelley: 'We'll give Naleigh sibling'

Josh Kelley has revealed that he and Katherine Heigl plan to expand their family in the near future.

The singer and wife Heigl adopted their daughter Naleigh from Korea in September 2009, an experience which he confessed has changed his life as well as his music career.

"[As] I was writing for [my new] album, we adopted a little baby girl and then I had everything under the sun to write about. I love being a dad and writing about that," he told HitFix.com.

However, he expressed disappointment that the 2-year-old was not impressed by a lullaby he wrote in her honour entitled 'Naleigh Moon', saying: "Right now, my pretty song gets beat out by the Wiggles and Yo Gabba Gabba."

He also insisted that he and Heigl are ready to give their daughter a sibling.

"We're definitely going to give Naleigh a little friend. She needs a buddy," he added.

Heigl previously admitted that she never expected Kelley to be a good father.
