Actress Kareena Kapoor Khan has given birth to her 'third child'.

No, it's not what you're thinking.

"So, what's been baking?" – In her words, it's her new book which is like her third baby, 'Kareena Kapoor Khan's Pregnancy Bible'.

Published by Juggernaut Books, it chronicles Kareena Kapoor's experiences through her two pregnancies.

Talking about her pregnancy, she said, "This has been quite the journey… both my pregnancies and writing my Pregnancy Bible. There were good days and bad days; some days I was raring to go to work and others where I struggled to get out of bed. This book is a very personal account of what I experienced both physically and emotionally through both my pregnancies."

The actress wrote about the book in a series of posts.

"I can’t believe that I actually agreed to write this book… but here it is. We all have our own unique experiences as expectant mothers, but there are some similarities and with this book, I’m sharing my experiences and learnings, and hope that in some way this will help you on your journey towards motherhood," she wrote.

Before launching her book, the actress had posted a picture of herself holding a sonogram report. "Been working on something exciting... but it's not what you're thinking," she had said.

Kareena and her husband-actor Saif Ali Khan welcomed their second child, a baby boy in February this year. Their first child Taimur Ali Khan was born in 2016.
