Katrina Kaif's sister Isabelle and Harshvardhan Kapoor were recently spotted together. Their outing set tongues wagging. While few think there's something brewing between the two, some feel the duo might soon collaborate for a new project.

But very few know that Isabelle Kaif and Harshvardhan Kapoor are said to be buddies and have known each other for long. They took their first steps in acting with Steven Roy Thomas' short film, Coming Home (2012). This happened when they were studying acting in New York. They have been in touch ever since.
