Jessica Simpson's Son Ace Adorably Cradles His Cousin Jagger

It doesn't get much cuter than this pic.
Jessica Simpson shared a photo on Sunday of her 2-year-old son, Ace, cradling Ashlee Simpson's baby, Jagger. "Ace and Jagger #COUSINS," she captioned the sweet moment.

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.

In September, Jessica spoke with ET about her new nephew and revealed that Ace isn't the only one in love with his cousin. "Jagger just came over to see me, Maxwell and Ace the other day and she's so tiny and so sweet!" she gushed. "And Maxwell is just obsessed! She has baby dolls, she wants to be a mom already. She's a care taker!"
