Filmmaker Boney Kapoor's kids Arjun Kapoor and Janhvi Kapoor are both established film stars now. It seems like the brother sister duo are going to collaborate for an upcoming project. Janhvi Kapoor recently shared a boomerang clip on her Instagram story which featured his step brother Arjun Kapoor as well. Both of them seem very excited and pumped about the upcoming collaboration. She shared the story with a sticker that read, "Coming soon."

Arjun Kapoor reposted that story on his account and asked fans to guess what's up. He wrote, "What are we upto? Any guesses?" However, at last he asked fans to "Wait for it."

As far as such announcements and promotional stories go, their upcoming collaboration is probably just a commercial advert or something along those lines. Its highly improbable that it will a movie since that would've made alot of noise and the announcement wouldn't have been so subtle. To really find out what this cryptic post was about, all we can do it wait.
