Angelina Jolie showed off her seriously skinny frame at the Kung Fu Panda 3 premiere in LA today. The thin actress shocked fans and reporters with her almost skeletal legs and arms. Her simple black shift dress masked her thin frame underneath, but there was no hiding her leg-for-miles pins ... that are basically pin-thin!

The actress has gone through quite a health ordeal the past 12 months -- she had her ovaries removed as a preventative measure against cancer, after having a prophylactic double mastectomy in 2013. The procedure results in early menopause, though the mother-of-six was unlikely to have more biological children of her own with husband Brad Pitt.

So, Jolie is back for another round of Kung Fu -- and so were a few of her kids! Pax, 12, Zahara, 10, Shiloh, nine, and Knox, seven, all recorded animal noises for the film. "They were kind of shy," the 40-year-old actress told Entertainment Tonight. "They don't really want to be actors, but I didn't want them to miss the opportunity. They came in, and they had a lot of fun with it."

Kate Hudson and Lucy Liu also co-star. Kung Fu Panda 3 follows Po [Jack Black] as he reunites with his biological father [Bryan Cranston] and works to train a village of pandas to fight against an evil ancient spirit named Kai [J.K. Simmons] who is terrorizing China. The film hits theaters January 29.
