Break out the maternity wear because someone's getting pregnant on Grey's Anatomy!
Fan favorite couple Callie (Sara Ramirez) and Arizona (Jessica Capshaw) are going to have a baby on the ABC hit series. That's right, Sofia is going to be a big sister.
But before the odd cravings start, Calzona needs to make a major decision: who's going to be the one to get pregnant?!
We've got an exclusive sneak peek at tomorrow night's episode of Grey's, "Go It Alone," which finds the couple using an unusual method to make the oh-so-important decision...
So how do Callie and Arizona make the baby bump-centric call? Do they pick a name out of a hat? Do they play rock-paper-scissors? Or do they flip a coin? They do in fact use one of those three methods to make the decision, but you'll need to press play on our exclusive video above to find out!
While Calzona may be welcoming a new addition to their family soon, the Grey's family will be down a few members by season's end. Not only is Sandra Oh set to exit after 10 seasons as Cristina, but Tessa Ferrer and Gaius Charles will also not return as series regulars.
Grey's Anatomy airs Thursdays at 8 p.m. on ABC.
