Karan Johar, who celebrates his 51st birthday on Thursday and 25 years in Bollywood, gave a sneak peek at his upcoming film ‘Rocky Aur Rani Kii Prem Kahaani,’ starring Ranveer Singh and Alia Bhatt.

Karan celebrated his 25th year in the Hindi film industry by posting a video on Instagram. The video consisted of a montage of songs from ‘Kuch Kuch Hota Hai’ (1998), ‘Kabhi Khushi Kabhie Gham’ (2001), ‘My Name Is Khan’(2010), and ‘Ae Dil Hai Mushkil’ (2016).

In the clip, according to an IANS report, Karan says: “Love comes with its conflicts and challenges but it`s the most beautiful feeling in the world. As I look back on my journey of 25 years as a filmmaker, I`m filled with immense gratitude.

“What began as a small attempt to share stories of love, friendship, and family that resonated within me.

“But as each one of you embraced these stories and characters, love found a new meaning to me every day. As I complete 25 years in the industry, this love of yours has given wings to a new story, a new prem kahani (love story), a story that celebrates love like never before in all its beauty and grandeur.

“A film that I have been waiting to share with you for so long, it`s finally ready. See you at the movies where we celebrate family, love and so much more.”

In the BTS video from `Rocky Aur Rani Kii Prem Kahaani`, Alia was seen laughing with Karan.

Ranveer was seen playing with a white cushion. Dharmendra and Jaya Bachchan, sat next to each other, as Ranveer kissed the veteran actor’s hand.

Karan captioned the post: “Nothing but gratitude for the magical 25 years I have spent in the director`s chair. I learned, I grew, I wept, I laughed – I lived. And tomorrow, another piece of my heart will be yours to see and I could not be more ecstatic as I celebrate my birthday with you all.

“With a Kahani (story) that has prem (love) written all over it. See you tomorrow! #RockyAurRaniKiiPremKahaani first look out tomorrow! In cinemas 28th July.”
