'Grey's Anatomy's' Jessica Capshaw Pregnant: Will Dr. Robbins Be Expecting on the Show?

Jessica Capshaw is pregnant with her fourth child, announcing her happy news with a cute photo of her family on Instagram. The 39-year-old actress plays the role of Arizona Robbins on Grey's Anatomy. Capshaw's pregnancy should be an interesting storyline on the hospital drama, after her character Dr. Robbins suffered a miscarriage in Season 11 of the show.

 The holidays have certainly arrived...All of our lives are being added to by the lights, music and the cheer!! This year our family has reason to further broaden our smile...baby number four is on the way!! I am a lucky, lucky girl...

Capshaw's pregnancy announcement photo on social media shows her husband Christopher Gavigan, the co-founder of The Honest Company with Jessica Alba, along with their kids getting a Christmas tree.

The couple are already parents to three children – Luke, 7, Eve, 4, and Poppy, age 3.

Capshaw spoke about how she balanced being an actress and a mom in an interview with Good Housekeeping in 2011.

She said, "I love what I do and I think it shows. As my kids get older, they can see me as a mom who loves working," she said at the time. When asked what three words describe her as a parent, she replied: "Consistent, fun, [and] patient."

Capshaw talked to People magazine last year about her third child, Poppy, admitting her daughter had been throwing tantrums.

The actress explained, "[She] is experiencing a reckoning of being two that my other two did not have. So I feel very grateful that she’s my third so I have the wisdom and experience to know it’s all fine and will pass."

Grey's Anatomy returns to television on ABC on Feb. 11.
