ET sat down with Stacy “Fergie” Ferguson today in New York City as she promoted her new campaign as spokesperson for MAC Cosmetics’ AIDS Fund Global Youth Prevention Initiative.

Fergie opened up about planning her wedding to actor Josh Duhamel, “It’s a very happy time for me. I’m just enjoying this moment. I’m a romantic, but I don’t think traditional. Maybe I’ll have black roses!”

She also tells ET that while she and Duhamel were vacationing in Los Cabos, Mexico in December, they stayed at the same resort as newlyweds Katherine Heigl and Josh Kelley. Fergie says she and Kelley treated the group to an impromptu concert one evening, “I start singing Sublime and Josh came up behind me and started playing the drums!”

Fergie goes on to joke about choosing a wedding dress, “I could take Katie Heigl’s dress, but they would have to chop it in half, then maybe I could wear it!”
