Jennifer Winget and Karan Singh Grover are clearly not on good terms. If anything, they go out of their way to avoid each other at any chance possible.
According to Deccan Chronicle, this happened very recently when Jennifer was supposed to perform at a Holi event and she was asked to perform to Hate Story 3‘s Tu Ishq Mera, which happens to be KSG’s song. She immediately refused but since the organizers demanded it, she had to go ahead with it.
A source said:
Jennifer was scheduled to perform on Karan’s popular song Tu Ishq Mera from Hate story 3. The song was selected by the channel. But the moment she found out that she was to perform on that song, she put her foot down and refused to do the act. However, after a lot of convincing from the events committee, she finally agreed to perform on the song. But again during the final performance, the actress got emotional and took an hour long break to resume.
