Hailey Bieber looked seriously hot while posing for the cover of GQ's 2025 Men of the Year issue. Bieber, 28, showed off her figure in a sexy barely-there swimsuit while posing on the cover of the magazine on Tuesday, November 11. In one shot, Bieber turned up the heat in a black number featuring a plunging neckline and halter straps by Saint Laurent. The rest of the look, which retails for $1,100, was finished with high-cut legs and an open back. Bieber made the look even hotter with purple heels finished with a lace-up design.
