Kajol made her debut in Tamil films with Rajiv Menon's "Minsaara Kanavu" in 1997, which saw her in the role of an aspiring nun, Priya, opposite Arvind Swamy and Prabhu Deva.
The actress although had an incredible experience working in the "VIP 2" alongside Dhanush and director Soundarya Rajinikanth, she said she found the process of learning her lines in Tamil quite difficult.
"Acting is a little more difficult in a language that you don't understand, like Tamil. It was a process for the first two days. I saw my scene paper, and I was like, 'Okay. You could take somebody else for the film now.'
The actress said it's been an amazing journey working in a Tamil film after so long.
