The photo looked absolutely stunning. Penelope was on the left looking straight towards her mother as she took the picture.

Brother Reign was sandwiched in the middle, appearing to be listening to something Mason was saying.

Being the oldest of the siblings, Mason put a protective arm around his lilttle brother as he pointed towards the camera with his left hand.
