There's a baby in Camilla Luddington's baby carriage!

The "Grey's Anatomy" star, who portrays Jo Wilson on the long-running ABC series, took to Twitter to spill some of the details surrounding the exciting news, including if she knew the gender.

As it turns out, fans will just have to wait until the baby is born or until mom and dad decide to share when it comes to whether the couple is having a girl or a boy.

Luddington announced her pregnancy in an endearing Instagram photo on Monday.

Alongside a photo of herself showing off her belly as Disney's Cinderella looks excitedly at her growing bump, the 36-year-old hilariously wrote, "Me: "I’m just gonna do a super casual pregnancy announcement." Also me: "I NEED PRINCESSES!!!!!!."

The growing bundle of joy will be the second child for Luddington and her husband, actor Matt Alan, who married in August 2019 and welcomed a daughter, Hayden, in April 2017.

"Okay so... Matt and I are so happy to fiiiiinally post after months of "hiding" that i am pregnant!" Luddington's announcement continued.

"We are beyond excited to add to our little family and give Hayden a sibling," she added before revealing that she's also been plagued with morning sickness that lasts all throughout the day. Constant nausea hasn't put a damper on their excitement though.

"... in all seriousness, we feel so lucky and I can’t wait to bring you guys along for the remaining months of this baby #2 journey!! *Shout out to the one and only Cinderella for helping me with this pic yesterday," Luddington concluded.
