Nargis Fakhri didn't know how to ride a bike. However, since director Imtiaz Ali wanted to shoot a sequence for Rockstar - where she rode a bike with Ranbir Kapoor riding pillion - she was game to learn it.

After just half an hour of practice, Nargis claimed she could take the shot.

Ranbir wasn't so confident though. He had his heart in his mouth when asked to ride with her.

Thankfully, the actress proved to be a fast hand at learning stuff and took the actor zipping down the road!
