"I have been a big fan of hers, big admirer. I remember when she got married, I also cried. So, it would be great fun working with her. But I don't know whether they have confirmed it yet," he added.
Yeh Jawani Hai Deewani, which is being directed by Ayan Mukherjee, will see Ranbir romancing his ex-flame Deepika Padukone when it hits screens May 31.
He says he is proud to see Deepika doing so well in her career.
"It's always great to see someone whom you have been so close to reach where she has because of her hard work, resilience, vision and intelligence. I am very proud of everything she has achieved," said Ranbir.
