Hailey appears in another gorgeous photo clutching a delicate white lily blossom while sporting a sleek black outfit complete with a baby bump. This partnership obviously extends beyond a simple ad campaign.

Hailey states, "I'm excited to be one of the women representing this generation and to be a part of this project during such a special time in my life," in response to her decision to work with YSL at this particular moment.

"I am very happy to be a part of this project because it allows us to show the strengths in self-ownership, confidence, and diversity," the woman goes on.

After starring in the summer advertisements earlier this year, Hailey is back with YSL with this partnership.
