Actress Sonakshi Sinha left the crew of a forthcoming movie surprised when she took off on a horse riding session out of the blue.

The sporty and fun-loving actress was shooting for a scene for her film with Arjun Kapoor when she saw horses around and she got on one of them and went for a ride all on her own.

A source said: "There were horses on the set for a mela (fair) scene and she absolutely loves horses. Since there was some time for the scene to start, she went ahead and rode one of the horses and it was for some good 15 minutes.

"In fact, not many know that Sonakshi is a trained horse rider and she used to ride from the age of 10 to 14."
