Katrina Kaif with sister Isabelle

Now that Katrina Kaif's sister Isabelle is the face of a cosmetic brand and is waiting to debut in Bollywood, all eyes are on her and her surname. She is referring to herself as Isabelle Kaif. Now that's a bit strange. When Kat began in Bollywood with Kaizad Gustad's Boom (2003), she was Katrina Turquotte.
