Watch: Sonu Nigam performs the upcoming Rocky Aur Rani Kii Prem Kahaani song Ro Lein De in the presence of Ranveer Singh and Alia Bhatt

The promotional tour for Rocky Aur Rani Kii Prem Kahaani continues, and one of the stops was a musical evening held in Mumbai. The lead actors, Ranveer Singh and Alia Bhatt, along with music composer Pritam Chakraborty and singers Sonu Nigam and Jonita Gandhi, were part of the event.

Three songs are out from Rocky Aur Rani Kii Prem Kahaani, and the fourth song is underway. Interestingly, Sonu crooned the track titled Ro Lein De at the event, and it's a song worth the wait.

It's being said that the song can be watched for the first time only on the big screen in Rocky Aur Rani Kii Prem Kahaani.

Check out the videos from the event below:

Meanwhile, Ranveer was also spotted performing Shah Rukh Khan's megahit Yeh Dil Deewana from the film Pardes at the promotional event on Friday night.

At one point during the event, the star praised Sonu Nigam and asked, "Anybody want to see an imitation of Sonu Nigam?" The singer can sound like any vocalist from any era; he's gifted in a unique way. The clincher, though, is that Ranveer can also sing like Sonu Nigam, he claimed. The actor received applause from the crowd.

While chatting with Sonu Nigam, Ranveer asked, "Many years ago you made a very naughty joke about me and my wife; do you remember that? To aaj mein lunga Badla."

The actor then sang Yeh Dil Deewana in a Sonu Nigam impression for the crowd. Subhash Ghai's 1997 love drama Pardes, which also starred Mahima Chaudhry, Apurva Agnihotri, Amrish Puri, and Alok Nath, contained the iconic single featuring Shah Rukh Khan. Nadeem Shravan composed the song, and Sonu Nigam sang the lyrics written by Anand Bakshi.

Meanwhile, Rocky Aur Rani Kii Prem Kahaani, directed by Karan Johar and starring Dharmendra, Jaya Bachchan, and Shabana Azmi, will premiere on July 28.

The trailer gave us a glimpse into the very different worlds of Rocky Randhawa and Rani Chatterjee. Rani is from a Bengali family that places a premium on education and information, in contrast to Rocky's well-to-do Punjabi background. And they fall in love, only to discover that their families are not compatible. Then, Rocky and Rani decide to impress their respective families by temporarily switching places.
