Actor Randeep Hooda had a hard time trying to lip-sync with the romantic song "Hasratein" from his forthcoming film "Murder 3", until choreographer Rajeev Surti came to his rescue.

"Rajeev went up to Randeep and suggested they do a pre-rehearsal for the song," said a source from the unit.

Randeep agreed to it, met Surti a day before the shoot and went through rigorous rehearsal. After an hour of gruelling practice, Randeep was confident he had mastered his lip-sync with the song.

When the shooting began the next day, everyone was anxious about how the shoot would go through as they knew the problem Randeep faced.

But as soon as the shoot started and the song was played, Randeep shifted into another gear and gave a perfect shot, the source added.
