Well, you might never have heard about this Bachchan girl ever before. So, let us introduce her to you all. Naina is Abhishek Bachchan's cousin and the youngest of Ajitabh's (Amitabh Bachchan's brother) daughters. In other words, Naina is Aishwarya's little sis-in-law.
Mid Day reports, "They are still in that 'getting to know each other better' phase and want to spend more and more time together. Kunal's continuous shoots have played spoilsport and have kept him away from his ladylove who lives in Delhi."
“So Kunal decided to take her along for the London shoot, which will last for 10 days. This is a perfect opportunity for them to spend some quality together away from the family and media glare," the source added.
