It's the first child for the Broadway headliner and former Smash star and her musician husband, who married last November.
The couple have made no secret of how excited they are to expand their family. In an interview last month with our own Goodyblog, Hilty said the nursery was all ready for baby and all decked out in Shabby Chic pastel colors. She also revealed that she and Gallagher have been exposing their kiddo to music in utero -- "Second Hand White Baby Grand" from Smash has been baby Viola's get-moving song.
Congratulations to the new family!
