Sinha is rumoured to have described Kapoor as primarily a style icon instead of an actress.
Kapoor told The Times of India: "I have learnt to be blasé about these things because those very same actresses are hiring stylists and wanting to dress like me. They hire my stylists and make-up artists and tell them that they want to do the same thing.
"I know Sonakshi and I love her. She's a good girl compared to the rest. She's grown up in my house so I don't think she meant it in that way. Even I said plenty of foolish things when I was at that age. I give everyone the benefit of doubt.
"If she wanted to clear it up she would have called me. I haven't done anything wrong so I don't need to check with her. I really don't care if she's said it or not.
"I won't be working with her so what's the need to clear the air? Even if I do work with her, everything will be forgotten by then. That's the way the industry works. Nobody holds grudges. There's a fight and the next day we hug and make up."
In January, Kapoor admitted that her wardrobe makes her look better than she would otherwise.
However, the 26-year-old said that she is too young to have an "iconic" dress sense.
