Khan was allegedly involved in a scuffle with South Africa-based Indian businessman Iqbal Sharma in Wasabi, the Japanese restaurant at the Taj Mahal Palace hotel in Colaba.
Speaking to The Times of India, Kapoor said: "I haven't spoken about what happened that night, but now I feel I should because whatever is being said is completely one-sided.
"This man (Iqbal Sharma) is publicity-hungry. How can a man with a broken nose and jaw speak continuously on TV for more than ten hours?"
Sharma alleged that Saif abused and assaulted him and his father-in-law and filed a complaint at the Colaba police station.
The actress went on to defend her Agent Vinod co-star, saying: "Saif was also hit and has a swollen eye. He has given a statement and each one of us stands by it.
"We were witness to what happened and this is a sure case of Saif being targeted because of his celebrity status. It's disgusting!"
Khan claims he was provoked and was acting in self-defence.
