The singer looked ravishing in a skin-tight leopard print dress that showed off her recent weight loss. It is also worth mentioning that pictures from the party are rare and strictly forbidden. The party goer shared the snap and mentioned that this was the only pic that made it out of the private event. She described a scene where celebrities where letting loose without the fear of being photographed and said that Adele was letting her hair down. Well, she metaphorically let her hair down because in reality it was pinned up in several cute buns.
