John Abraham's co-actor in 'Rocky Handsome', child actor Diya Chalwad, is also a gymnast.

The youngster would often display to the fitness-conscious star how to do cart-wheels and other forms of gymnastics.

John was quite impressed not only with her agility, but also by how she memorised her lines by heart. Once John even forgot a line during a scene, but little Diya caught him. Ouch.
