Katrina Kaif's Sister After Six Month Launch Bollywood: Katrina Kaif’s younger sister Isabelle  is not coming to Bollywood for the next six months at least. Kat had already begun talking to some of her film-makers about launching Isabelle in Bollywood. However during Isabelle’s stay with Kat in Spain, she is said to have told her older sibling that after she finishes her acting course in New York, she would like to continue staying in the Big Apple and audition for some very interesting roles in the West. Those auditions could continue for a period of six months and above. It is only after she has realised those dreams, will Isabelle consider moving to Mumbai.
