Ranbir Kapoor admitted in an interview that he had major crush on Aishwarya Rai Bachchan since teenager and he was nervous about working with her. 

In Ranbir's words, "I had just passed out of the 10th standard. Pitaji ki film thi – Aa Ab Laut Chalein, usmein unhone (Aishwarya) acting kari thi and main film main ek assistant director tha. Wahin hamari dosti ho gai thi. Of course, Aishwarya Rai hai, uss age main bhi aap thode enamoured ho jaate ho. Woh age main bhi aapko idea ho jata hai ki ladki kya hoti hai, ladki se ishq hota hai. So I think woh jo mera pehla dil toota tha, woh mera dil halka sa Aishwarya Rai ke liye toota tha!"

On asking about nervousness to act hot scenes with aish, he said, "Sharam aati thi, mere haath shiver hote the. Kabhi kabhi main unke gaal ko touch karne main jhijhakta tha. Phir unhone hi bola, ‘Listen, what’s wrong with you? We are acting, do it properly.’ Phir maine socha, kabhi aisa mauka milega nahi, so maine bhi mauke pe chauka maar diya!"
