I love the strong emotions in this picture. Typically the lioness is the one in charge, the one who hunts and takes care of the babies but here she surrenders, gives up her power momentarily to engage to the lion's sweet play.
The White Lions are rare animals found in South Africa. They are not albinos, but a inherited scarcity, unique to one common region on the glob. Their white color is a result of rare color mutation of the Kruger breed of lion.
