Zoa, however, made light of the incident, saying "I am human and it happens".
Zoa, who made her Bollywood debut in Shahrukh Khan`s home production `Always Kabhi Kabhi`, was the showstopper for designer Payal Kothari at the Lakme Fashion Week.
Wearing an orange coloured short dress with high heels, teamed with accessories symbolising an African tribe, she looked stunning. "Ya...I know I got a bit slipped and it is OK. I am human and it happens. The best part is I enjoyed walking on the ramp," Zoa, daughter of film producer Karim Morani, told PTI.
"I was very much comfortable wearing this outfit. I just loved the tribal designs and the footwear," she said.
Payal, who hails from Africa, showcased her collection `Veruschka`, which is inspired by traditional African art, on day-two of LFW on Saturday evening.
