Interestingly that letter which was written by Deepika's father was published in a book, authored by Sudha Menon. Not many were aware about this initially and hence when they got to know, many speculated that the actress should have credited the book and the author for letting her read the letter.
However, a source close to the actress informs us, "When Deepika was being praised for the letter she did tell people about the letter being part of the book. In fact, Deepika even thanked the author for allowing her to read out the letter to the World."
The source adds, "Also, whether a part of the book or not, the fact remains that the letter has been written by Deepika's father."
And though many aren't aware, but author Sudha Menon had also quoted to a leading daily, just after the letter read by Deepika Padukone had gone viral, that she was touched by Deepika's gesture for reading the letter from her book Legacy.
