Actor Arjun Kapoor, who will be seen romancing actress Kareena Kapoor Khan in director R. Balki's upcoming film "Ki and Ka", says he was 15 years old when the "Bajrangi Bhaijaan" actress made her film debut.

"I was 15 years old when Kareena made her debut and I was in 10th standard. I had met her before her debut so I knew her and she has not changed since then. I still make fun of her like I used to make fun of her before," Arjun said.

Kareena made her Hindi film debut in the 2000 film "Refugee".

"She is a phenomenal actor to work with, and to stand in front of her in a same screen is amazing because she is fantastic. She gives her 200 percent and she can switch on and off," he added.


In `Ki and Ka`, Arjun will be seen playing an IIT graduate and a house husband to Kareena's character Kia, an ambitious career-oriented woman.

Arjun reveals that his friendship with Kareena played a pivotal role in making their on-screen chemistry come alive.

"You need an actor whom you are very comfortable with because the marriage should look real on screen. Already, the concept is so bizarre, so you need to show that compatibility," he added.

The romantic comedy is slated to hit the screens on April 1.
