If you need a love song, who do you call? Atif Aslam, and that's exactly what Salman Khan did for his film Tiger Zinda Hai.

Track 'Dil Diyan Gallan' features Salman and Katrina Kaif getting intimate as they bond in the mountains. Salman is the hopeless romantic, and the two mirror a high school kind of romance.

The song has a Yash Chopra feel to it, something which the Tiger Zinda Hai director Ali Abbas Zafar wanted to achieve. "I have always wanted to pay a tribute to the classic Yash Chopra romantic songs which I have grown up loving. And I’m thrilled that I finally got that song in 'Dil Diyan Gallan,'" he said.

Speaking more about the song, he added, " It is a romantic track that captures the beauty of a mature love story. We have filmed [the song] in an old school, vintage way to bring alive the romance that two mature people share. It is like a classic Yash Chopra song."

Tiger Zinda Hai releases 22 December.
