The tender photo had an antique, sepia tone over it with an orange frame surrounding it.

Jessica recently took Ace to the golf range and shared video of the natural athlete flaunting his skills.

'Already borrowing his dad’s clubs #ACEKNUTE,' she wrote along with a video of her son swinging at the ball.
