Before the show, Fergie met with fans and shared footage on her Instagram story.

“I want to thank all of you in your different ways. Whether it be helping online with all the naysayers or just helping me with the fashion or just sometimes being there for me when I need to read something that’s filled with love,” she said in the clip. “Thank you so much from the bottom of my heart. I’m so glad this whole race has been to get here … I thank you so much, everybody, I appreciate you so much. I’m so blessed.”

FYI: Fergie is wearing Fergie Footwear boots and Stefere jewelry.
