Olivia Munn kept it simple in an all-black outfit as she left a gym in Los Angeles after as reported a high-intensity exercise session. The actress wore a black t-shirt with matching leggings and black sliders. Olivia had her long brunette hair straight down around her shoulders and let her natural beauty shine without make-up. She was carrying a white hydrating water bottle, cellphone, and a black backpack while accessorized with silver aviator sunglasses as she headed to her white Tesla SUV.
