"Ohh Teri" has newcomers in the cast and it will come out next year.
"It's too early right now as we are still working on the song track. We have not approached Katrina, but Salman has been involved with the project right from the beginning," Atul, who is married to Salman's sister Alvira, told IANS.
"If I can't justify somebody's participation, I will not cast them. Katrina has always been with us she is our well-wisher and a wonderful person, so let's see how thing shapes up," he said.
He had earlier directed Salman in "Dil Ne Jise Apna Kaha" and "Hello".
"In 'Bodyguard', both of them looked good and it worked, so a person's participation should be justified," he said.
