Kriti Sanon is 'very much protective' about little sister Nupur

"I am 5 years older than Nupur ...She has always been like my baby. I have seen her growing up...and now seeing her achieving her dreams, performing in front of the camera make me very much emotional. I am very much protective and possessive about her," Kriti told IANS.

And like every sibling, they fight with each other, too!

"Our bond is like any sister duo would have. We are like friends. We argue..we talk...we fight and we fight on stupid things. Nupur is my biggest cheerer. Whenever I feel low she lifts up my mood and does her best to make me happy," she added.

Nupur, who is a singer, made her acting debut opposite Akshay Kumar in B Praak's music video, titled "Filhall".
