Years later, Ranbir finally got to work with Aishwarya. “The experience has been great,” the actor had said while speaking to Fever 104 FM. “Which actor wouldn’t want to romance her? It was a historic moment in my career when Karan told me that he would be casting her. I thought she would say no and wouldn’t act with me.”

Ranbir was the assistant director on Aa Ab Laut Chalen. Speaking about it, he had said, “I have been friends with her since that time. When Aishwarya got married to Abhishek, I spent a lot of time with her during those days as well.”

Ranbir's mother Neetu Kapoor had also once shared an old picture of Ranbir trying to paint a picture of Aishwarya on the movie's sets. "The great Artist at work #throwback #aaablautchalen #ranbir #ashwariya," she had written.

Ranbir is currently busy with multiple projects. He has Brahmastra with girlfriend Alia Bhatt, another film with Sandeep Reddy Vanga, titled Animal. He also has Shamshera with Sanjay Dutt. Aishwarya meanwhile has Ponniyin Selvan with Mani Ratnam.
