Katherine Heigl Shares Sonogram of Her Son on Instagram After Pregnancy Reveal

The actress and her husband of eight years, musician Josh Kelley, are expecting their third child  a boy!  in January, the couple confirm to PEOPLE exclusively.

Their son will join big sisters Adalaide Marie Hope, 4, and Naleigh Moon, 7.

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

“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 jokes. “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.”

We’re so excited people!!! What an awesome journey!!!” hecaptioned a photo of the pair. “Can’t wait to hold this little nugget. Not sure where they found this photo but I was 25 pounds heavier then.”

Heigl, 37, and Kelley are already parents to daughters Naleigh, 7, and Adalaide, 4. (They tied the knot in 2007 after meeting on the set of his music video for “Only You” in 2005.)

Heigl, 37, and New Lane Road singer Kelley, 36, adopted Naleigh from South Korea in September 2009 when she was 9 months old. Heigl, whose sister Margaret was also adopted from Korea, created the name Naleigh as a combination of Nancy, her mom’s name, and Leigh, Margaret’s middle name.


Naleigh was born with a congenital heart problem that was fixed via open-heart surgery before she left Korea according to a Harper’s Bazaar story from 2010. “Her heart is 100 percent fine now,” Heigl told the magazine at the time.

“The whole pregnancy thing is new to me, but the thrill of having a baby is not,” she explained. The couple adopted Naleigh in 2009 and Adalaide in 2012. “We’ve known for a while that we wanted to add to our family and frankly didn’t really care how we chose to do that. We were considering adoption again, fostering or pregnancy if possible. Seeing as I have never been pregnant and, as my OB/GYN reminded me last year, I’m of advanced maternal age, I wasn’t sure pregnancy was even in the cards for us. Turns out it was very much in the cards!”

The Knocked Up actress added that she’s never considered herself “particularly patient,” but that she knows their son will be worth the wait.
