She posted the makeup-free selfie for an empowering reason, which was inspired by model Kate Upton. "Spreading some self love today with zero filter and zero makeup for my girl @KateUpton," she said. "She's on a mission to encourage everyone to feel strong and love themselves *as they are*... and I'm so honored to help spread that message. Take a second to show the real you. Tag someone you admire and pass it on ❤️💪#ShareStrong"
