Someone's got a case of the giggles—and this time, it's not Kelly Ripa.
Earlier this week, Mandy Moore shared a sweet clip of her 9-month-old son, Ozzie, being entertained by his big brother, Gus, 2. The This Is Us actress, 39, cradled her youngest boy in her arms while Gus was preoccupied with the door, and Ozzie just couldn't stop laughing as he looked at his sibling, who was wearing his baseball cap backward. Moore captioned the video, "Ozzie is Gus’s biggest fan."
