Photorealistic Gym Mirror Selfie of Two Subjects

A detailed prompt for generating a photorealistic mirror selfie featuring two subjects (Sydney Sweeney and Kylie Jenner likenesses) posing playfully in a modern gym. It specifies their athletic attire (matching scrunch-butt leggings in lavender and orange), the composition (backs to camera, full reflection visible), and the environment (spacious gym with cardio machines and bright overhead lighting).
