Shortly after the sweet pic was posted, she caught Ace getting into some mischief. "'Mom and Dad will never know' #WHENABEAUTIFULSONHIDES #ACEKNUTE," she said of her son hiding in a basket.

Jessica also got a lesson in how to pose for a selfie from her daughter Maxwell. "Be cool and kiss the camera mom," the 3-year-old told her mother.
