It is to be mentioned, Twinkle Khanna, who has earned a name as an author, has got into an agreement with Penguin to bring out three books, of which one is already done.
It is nothing unusual among Bollywood stars to post testimonies about other stars on Twitter and Karan Johar did the same for his childhood friend, Twinkle Khanna.
Karan Johar posted a testimony about Twinkle Khanna on Twitter saying, "She is the discovery of the decade". MrsFunnyBones retweeted the same adding a tinge of sarcasm as she included Alia Bhatt into the Twitter conversation.
Twinkle Khanna replied, "Not discovery of a lifetime? Guess @karanjohar saved that title for @aliaa08 so I will settle for this decade thing:)".
Soon, it turned into a funny yet sarcastic series of comments as Karan and Alia replied Twinkle Khanna with almost equal amount of sarcasm.
