Shahid Kapoor's mother Neelima Azeem had revealed the reason behind the name 'Zain'. Talking about naming Shahid and Mira's second baby Zain, she said, "I think it is the name that has been running in everybody's mind for a long time but obviously, it was his parents who decided to call him Zain. But this name has been there in the family. I have a nephew with the same name. It is a beautiful name."

Amid Zain Kapoor's first Diwali celebration, Shahid Kapoor's wife Mira Rajput Kapoor gave their fans a cute bundle of surprise. The actor's wife uploaded this picture - a first-ever glimpse of their son Zain Kapoor on Instagram, and captioned it, "Hello World [sic]."

Shahid Kapoor shared this picture of munchkin Zain Kapoor. A beautiful father-son moment captured that will surely make you fall in love with it. Shahid is smiling with happiness, while Zain's playful nature is evident in the frame. Shahid captioned the image: "The sun! [sic]"

Mira Rajput, staying true to when she said, "I'm not a regular mom, I am a cool mom", shared this photo of baby boy Zain on Instagram. Zain's hoodie reads, "I'm limited edition", and we couldn't agree more!

Last year, roughly during Kabir Singh's promotions, Shahid Kapoor spoke on Neha Dhupia's chat show about Zain. He said the kid is "really good looking" and has got features like his wife Mira. During a candid conversation, host Neha Dhupia asked Shahid what it is like to be a father to a baby boy. Shahid said, "He is so good looking, I am fanboying him all day."

Neha asked him, "Is it like a mini-me moment for you?" Shahid said: "Not at all. He is way better looking than me. He has got (features from) both of us (Mira and I). Because he is a boy and he was born with a lot of hair, everybody thinks he looks similar to me, but actually, I think his features are a lot more like Mira's. He has got sharper features which is nice for a boy and I think both of them are like a little bit of a mixture of both of us. But he is just really good looking."

Mira Rajput Kapoor shared this adorable silhouette picture of Misha and Zain, beachside, and shared a note that read: Creator of life and light, we praise thee this day for the beauty of thy world, for sunshine and flowers, storm-cloud and starry night, for the radiance of dawn and the last smouldering calm of the sunset.

Sibling goals! The caption of this picture by Mira Rajput will surely make you say 'Aww'.
