Prior to giving birth to Delta, Bell hinted that the baby was coming soon because listening to Josh Groban was making her cry.

It was revealed back in June that the married couple had another child on the way. “The whole family is beyond excited,” a rep for the pair told Us Weekly at the time.

Bell and Shepard, who wed in 2013, are also parents to 20-month-old daughter Lincoln.
