While shooting for Farah Khan’s forthcoming film Tees Mar Khan, Kats developed severe stomach cramps. The reason may be due to exhaustion, as Kats had been rehearsing hard for the hot number Sheela Ki Jawaani, for seven days continuously.

According to a source, while rehearsing the belly dance, Katrina yelled out loud, sending Farah Khan and the dance team in panic. When Farah realized that Katrina’s body couldn’t take the rehearsals anymore, she called for an early pack-up and also gave a day’s holiday to the actress to rest.

Now, the song will begin shooting from August 21. The number will have Katrina doing some breathtaking belly-dance steps. She will be at par with Shakira. She has never looked this hot.
