According to recent reports, Saif's mother Sharmila Tagore said that the couple would be tying the knot on October 16.
Speaking to The Times of India , however, the Life Goes On actress said: "I am quite confused myself. I know it is happening with the people in question, but they haven't set the date or talked about it. I think it is happening imminently."
Soha added that she will be performing her "sisterly duties" on the day as instructed.
"I'm not getting very involved at this stage. When I'm told to conduct my sisterly duties, I will do as I am told," she said.
"I don't know what I am wearing. When the day comes, I will wear whatever my mother says. She is the one who is in control of everything - from the venues to the clothes. She will decide what I'm wearing and I will quietly put it on."
Soha, who is reportedly engaged to actor Kunal Khemu, is said to have no plans to marry as yet.
