/> In case you didn't know Katrina Kaif is very accident prone.

A month ago Ranbir Kapoor missed his cue and slapped Katrina Kaif so hard on the sets of Raj Kumar Santoshi's Ajab Prem Ki Gazab Kahani, her face ballooned and shooting had to be cancelled.

Last week Katrina got her leg rather badly injured at Film City in Mumbai while shooting for Priyadarshan's Dhan Dhana Dhan.

According to members of the cast, Katrina was doing an underwater sequence with Akshay Kumar when her foot got tangled under water.

Says a source, "The more she tried to extricate herself the more her leg got tangled. She tried to scream for help. But because of the noise on the sets including the stunt co-ordinators who were shouting instructions to the entire cast, no one heard Katrina's screams of pain."

Finally it was up to the film's leading man Akshay Kumar to do the needful.

Says the source, "Akshay saw Katrina was in trouble. He quickly swam to her and got her out of the tangle."

Katrina leg was bruised and bloodied. Panic prevailed on Priyan's sets for a while until medicos arrived and took care of Katrina's wounded leg.

"It could've been worse, " shudders the source, "But tetanus shots and sedatives have eased her pain." When contacted Katrina tries to downplay the incident. "It was nothing.I hurt my leg. Nothing serious at all. There was a cut that hasn't healed as yet. So I'm in a lot of pain."
