Katherine Heigl has some delightful news to share: she and her husband are expecting a bouncing baby boy in January!

“We are expecting a third addition to our tribe!” the expecting mom announced on her blog.

Heigl and her husband, singer Josh Kelley, adopted two daughters, Naleigh and Adalaide.

This is Heigl’s first pregnancy.

“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,” wrote Heigl.

Heigl posted several photos to Instagram and Twitter with the big announcement.

Congratulations to the growing family!
