Ellen Pompeo baby was the topic of her recent interview with Jimmy Kimmel on Thursday's episode of "Jimmy Kimmel Live." She talked about a few details regarding her newborn daughter Sienna May and the confidential surrogacy process.

She said, "She was born two months ago. I've done it before. The covert thing is kind of fun. This baby was born via surrogate. So, I felt an obligation to keep the surrogate's privacy. That was of utmost importance to me."

The star of "Grey's Anatomy" has recently confirmed that she had secretly welcomed her second child with her husband, Chris Ivery. She wrote on her official Instagram account alongside an amazingly adorable picture of her newborn, "Sienna May Ivery, welcome to the world. We love you more than words can say." She also gave her fans a sneak peek into baby Sienna's nursery on Thursday, as seen in Architectural Digest's November 2014 issue.

Kimmel, on the other hand, seemed to have been much more curious about the actual surrogacy process. He asked Pompeo, Pardon my ignorance on this. When you have the baby through a surrogate, does your husband, uh, visit her in the motel room?"

Ellen Pompeo was laughing when she answered. She told Kimmel, "No, no." She explained the surrogacy process to Kimmel and to the rest of the audience who were there at the time, "I was present for the insemination. I held her hand. So, they take the sperm. Medically, Chris Ivery has to do what he has to do and provide what he has to provide. I had to provide something as well. You have to retrieve the egg. And then, they put it together in a dish - the lab technicians - and then they make the embryo. Then, they insert the embryo into the woman who will carry the child."
