Mohit and Udita have been dating for seven years, ever since the former directed the model-turned-actress in 2005 film "Zeher". They will tie the knot here Jan 29.
Emraan will join Mohit's real sister Smiley Suri for a dance performance at a post-wedding cocktail party Jan 31.
"Emraan and I will be performing on a special song for Mohit's cocktail party post his wedding. There is also a secret act planned, and I can't reveal much about it, " Smiley told.
"Emraan's son Ayaan and his wife Parveen will also be in the act, so we are all excited about it. There are going to be lot of surprises for Mohit on that day, " she added.
Smiley, who was a part of Mohit's film "Kalyug", is excited about her brother's temple wedding.
"The wedding will be held at the Hare Rama Hare Krishna temple. It will be a traditional wedding and we will be having a mehendi ceremony on Jan 28 at our place, " she said.
For now, she is busy arranging a designer for Mohit.
"Mohit is busy with his film right now. I won't be shocked if he lands up wearing a pair of jeans on his wedding. So I am trying my best to get a designer for him. We all are very excited and Mohit is my only brother, so I am all the more excited for his wedding, " she said.
