Dr. Arizona Robbins may have trouble wrapping her head around the idea of kids, but the actress who plays her is in full baby mode. She's expecting #2 soon!

Jessica Capshaw and husband Christopher Gavigan will welcome their second child later this year. "They are absolutely thrilled," the actress' rep told People.

We can imagine they are. What great news. Their son, Luke, will be three this year. Gavigan is the CEO of Healthy Child, Healthy World, a national non-profit.

Jessica Capshaw is about to be a mom ... again!

The Grey's Anatomy cast member is the daughter of Kate Capshaw and step-daughter of Steven Spielberg. Congratulations to Jessica, Christopher and Luke!

As for her character, will wedding or baby news be on the horizon for Arizona, one of our favorite recent show additions? Hopefully! We know Callie's up for it.

Either way, it's great to see the Grey's Anatomy baby boom continue in real life.
