Shah Rukh Khan romancing Kajol in Iceland is what dreams are made of.

The "Dilwale" song "Gerua" has garnered over a million hits in less than 12 hours, and the fans have declared it a hit on social media.

Trending on Twitter (#LoveAnthemOfDecadeGerua), the video captures the infectious chemistry this pair is known and loved for.

Composed by Pritam, sung by Arijit Singh and Antara Mitra, and penned by Amitabh Bhattacharya, the song will sure be remembered for its melody.

However, the beautifully done video didn't come easy for the cast or the crew. It was very challenging for SRK and Kajol as they had to shoot in freezing temperatures.

At the song launch, the superstar also revealed a little history about the aircraft he serenaded Kajol on.

"The place in Iceland is called as Black Beach. The plane there has a little history behind it. It was landed by a pilot there who ended up saving the lives of all passengers on board. No one was killed in the crash. It has remained there ever since. The plane is black as well. Justin Bieber recently skateboarded on the plane," The Indian Express quoted Shah Rukh as saying.
