Sasha looked straight at the camera, wrapping his arm around his mom’s shoulders and holding her tightly.

“Step #1,” the actress wrote atop the image. “Already [bawling] 😭😭😭.” She made sure to tag her teenager, who was wearing a white T-shirt, baggy blue jeans and a simple chain in the shot.

Watts, for her part, looked chic in an oversized beige blazer and a white collared shirt, which she paired with wide-leg blue jeans.
