On the Ash Replacement Controversy in Chalte Chalte (2003).
Source, in full
As a matter of fact, and I have said this before, I was the original choice for this role. Shah Rukh spoke to me about the film during Asoka. I didn’t have dates, so Ash replaced me. When she couldn’t do the film for whatever reason, Shah Rukh asked me to do it. I love Aamir and Shah Rukh in a different way. When Shah Rukh asks, I can’t say no.
