Actress Katrina Kaif, who features in the promotional video of Vijay Mallya's Indian Premier League (IPL) team 'Royal Challengers', surprised everyone when she played a prank while shooting the song.

She took the mike, changed her voice and announced that Katrina had fainted due to the non-stop shooting in the sweltering heat.

The shoot had started at 7 a.m. at the Brabourne Stadium in Mumbai owned by the Cricket Club of India (CCI).

The whole unit panicked and frantically started searching for her but couldn't find her for nearly half an hour. Director Sanjay Gupta and choreographer Bosco were tense since they had to finish the shoot in the limited time allotted by the authorities.

Everyone heaved a sigh of relief when they saw Katrina emerge, having a good laugh.

When contacted, Gupta laughed and said: "Hey who told you that? Katrina was lovely to work with."

Last year Katrina gave hits like "Namastey London", "Apne", "Welcome" and "Partner", and this year her film "Race" has done well at the box office.
