David and Christina Arquette Name Their New Baby After His Late Sister, Alexis

David Arquette and wife Christina McLarty are parents for the second time! The happy couple welcomed a son, Augustus Alexis Arquette, on Wednesday. David and Christina plan on calling him "Gus" for short but gave him his middle name as a heartfelt nod to the Scream actor's late sister, Alexis Arquette, who passed away in September at age 47. Baby Gus will join big brother Charlie, 2, and half-sister Coco, 12, whom David shares with ex-wife Courteney Cox. David gave his Instagram followers the first adorable peek at his new addition with a close-up shot of Gus, simply captioning it, "Augustus Alexis Arquette || March 8, 2017 @christinaarquette." We can't wait to see more photos of their growing family!
