The actress gave birth to daughter Keeva Jane on May 23, her rep told Us Weekly. Hannigan and her husband, actor Alexis Denisof, also have a 3-year-old daughter with an equally unusual name, Satyana.

Hannigan returned to Twitter today after a now-explained three -week absence to share a photo of one of Keeva’s hands. Needless to say, it was precious.
