The 35-year-old businesswoman was dressed in a pair of camouflage skinny jeans, white T-shirt, a studded leather jacket - and, as everyone now knows, a white thong.
As she bent over to pick up some items, she ended up showing off a lot more than bargained for and gave onlookers a clear shot of her bare bum and undies.
However, rather than pull her trousers back up to their proper place, she continued to walk to the cashier with the trousers still riding dangerously low.
Speaking to Prestige Hong Kong magazine, she said: "I can't begin to describe the feeling, I'm so excited and so thrilled for Nicky. She will be a wonderful mom and I want to be the best aunt I can be. I'm already shopping for my niece and can't wait to meet her soon."
She also opened up about the single life, admitting she's focusing on work right now rather than meeting someone.
"I see myself primarily as a businesswoman but also as a music artist, DJ and philanthropist. When I was little my parents and grandfather instilled a strong work ethic in me and encouraged me to pursue my dreams. I always knew that I wanted to have a global brand and to do more than one thing, so I really enjoy what I do and feel very lucky and fortunate."
