Pompeo broke the news on Twitter Thursday that she and husband Chris Ivery welcomed a second daughter, Sienna May.

"Sienna May Ivery welcome to the world," Pompeo, 44, wrote on Instagram, along with a sweet photo of her husband cuddling the baby. "We love you more than words can say."

Inside, Pompeo shares exclusive before-and-after photos of the family's newly renovated 16,000-square-foot Los Angeles home, as well as peek at the Sienna's nursery.

Working with Los Angeles decorator Martyn Lawrence Bullard, Pompeo took the building down to its studs, changing the home's layout, enlarging windows and swapping polished wood floors for vintage limestone pavers, reclaimed terra-cotta tiles and planks of textured French oak.
