Katherine Heigl and her husband Josh Kelley are expecting their third child together, according to PEOPLE.

“The Kelley clan is thrilled to announce that we are expecting a third addition to our family,” the couple said in a statement. “Raleigh and Adelaide could not be more excited to welcome their new sibling into the fold and Josh and I are overflowing with joy and gratitude.”

This marks Heigl's first pregnancy, and she expects to give birth to a baby boy in January.

“This is an incredibly exciting time for us filled with hope, anticipation, and hormones. Well, only I’m filled with hormones, but everyone in the family gets to enjoy them,” Heigl's statement continued. “We couldn’t be more excited to be able to finally share this news with our fans and are looking forward to continuing to share the journey with you all. xoxo, Katie and Josh."

Kelley posted about the announcement on Instagram, writing, "Well I guess the cats out the bag!!!! We're so excited people!!! What an awesome journey !!! Can't wait to hold this little nugget."

The couple -- who adopted their daughters Naleigh Moon from South Korea in 2009 and Adelaide Marie Hope domestically in 2010 -- always planned on having children, but Heigl was particularly adamant about adoption because of her sister Meg, who is from Korea.

“Josh and I started talking about it before we were even engaged,” Heigl said in a 2012 interview with Parent & Child. “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."
