Katrina Kaif's adventurous ways worry co-star Salman

 Salman Khan can't hold back his fondness for ex-flame, Katrina Kaif.  They gave us candid pictures and memorable quotes for each other at IIFA  in New York, they are hard to be missed on Bigg Boss and now audience  can't wait for their big screen reunion in Tiger Zinda Hai. Two stars are currently working together on the sequel of 2012 hit,  Ek Tha Tiger where Zoya aka Katrina Kaif will be seen doing action  scenes and stunts like Tiger Salman Khan. But that worries the  superstar. According to BollywoodLife report, Katrina was supposed to  perform a deep-sea diving stunt for the film. While the actress was game  for doing her own stunt, Salman wasn't too happy with that. He wanted  her to use a body double, worrying that she might hurt herself. But  Katrina Kaif who played a scuba diver instructor in Zindagi Na Milegi  Dobara was happy to go back into the ocean once again. She even shared  picture of her performing the stunt in Morocco. And by the looks of it Salman Khan doesn't need to worry, this fit and fabulous actress looks totally in control of the stunt.
