• Arbaaz Khan mistimed his step during a song sequence and moved ahead while Amrita Arora was leaning on him. She had a bad fall as a result

Mumbai, Aug 3: Amrita Arora gravely injured her knees while shooting for a song in Atul Agnihotri's Hello at Film City here.

The song required Amrita to lean on to brother-in-law and co-star Arbaaz Khan, as part of the choreographed steps. Arbaaz was supposed to move ahead later, but he mistimed his step and ran forward while Amrita was still leaning on him. This caused Amrita to fall on her knees.

Confirming the incident Amrita said, "I seriously injured both my knees. The pain was unbearable for me, but the entire incident turned out to be hilarious for the 200-odd junior artistes, unit members and Sohail (Khan) who could not control his laughter."

"Wicked that he is he kept rewinding to my terrible fall on the monitor just for everyone to watch and tease me. When I watched it I too could not control my laughter. The entire incident appeared like a comedy scene from a film," added Amrita.

However, things weren't so funny after half an hour when Amrita's knees turned black and blue. A doctor had to be called on the sets and she had to take a tetanus injection to prevent infection.
