The Chicago P.D. actress strips down for the men's magazine, wearing a mesh corset and, well, not too much else. But Bush is more than just a pretty face—she's a talented actress and an outspoken activist.
Bush, 31, uses social media to highlight a variety of causes and social issues. "I realized I could have a dinner party conversation with 15 people, and I could use Twitter to have that same conversation with a million," says the California native, who volunteers for Pencils of Promise and charity: water.
Given that she's consistently been on TV screens since 2003, the actress has amassed quite an online following. "Well, it's funny. It's not often that someone gets a job at 20 and then does it for a decade. Those are the years you're supposed to be growing and exploring new things," Bush says of her One Tree Hill days. "But this show [Chicago P.D.]? It feels like the job I was supposed to be doing."
