"I haven't gotten used to it yet, every time I look at it, it's still a surprise," She said. "I'm so happy."

"I just really want to enjoy this moment because I've always wanted to be on the cover so I'm just living it right now," she added, "but seeing the past models and where they've taken their careers, hopefully I can do the same or something like it."
