The actress, who has acted in about 10 Bollywood movies since winning the Miss India contest in 2001, said that it was just a prank, and that she had later admitted before people that she was behind it.
"You should have seen the expression on the guests' faces when Ken actually said that to them. They were just stunned and did not know how to react," a tabloid quoted her as saying.
"Later I told the guests that it was a prank that I had played on him," she added.
'Love Has No Languages' is based on a cross-cultural romance. It stars Jaitley as an Indian girl brought up in New Zealand who falls in love with Kiwi actor Ben Mitchell.
