Lia Cooper is an American trans adult performer with blonde hair, a tall frame, and a polished mainstream look that carried across studio and clip-platform work in the late 2010s and 2020s. She is known for trans solo, oral, topping, and trans-girl scenes, including work for Grooby and related studios. The memorable part is the calm, almost matter-of-fact way she takes over a scene once the flirting ends. Stop scrolling. Lia Cooper is on Creative Porn.
