Author Twinkle Khanna penned a sweet note for her daughter Nitara, who turned eight on Friday.

Twinkle took to Instagram and shared a couple of pictures of Nitara. "My little one turns 8! Along with all the strange and wonderful bits and bobs that seem to permeate her universe, the first copy of our children's book-When I Grow Up I Want To Be.. has also been presented to her-for a review:) I don't know what she wants to be when she grows up, all I know is that it's happening too fast. #BirthdayGirl," she wrote as caption.

Twinkle's B-Town friends dropped birthday wishes for Nitara in the comment section.
