Social media is taken by storm because of Thalapathy Vijay's birthday bash as the star turned 49 today. Meanwhile, it is raining 'Leo' updates. While the ravishing first look of Leo made its debut at midnight, now the makers have launched the first single as a treat to the fans.

Composed by Rockstar Anirudh, "Naa Ready" is a mass kuthu song in Thalapathy Vijay's voice and not to forget the rap by Asal Kolaar. Vishnu Edavan, the assistant director of the Leo maker Lokesh Kanagaraj, has penned the lines of the peppy number. This is yet another amazing, power-packed mass song from Ani's studio. The strong bass and vibe-worthy interludes are blasting through the speakers.

The lyric video features a young look of Thalapathy Vijay with his spell-binding dance moves. It has choreography by Dinesh master. Sanjay Dutt, Lokesh Kanagaraj, Mansoor Ali Khan and others were seen in the BTS clips in the video. The song is all set to rock on the silver screens. It is safe to say that the assets of Leo including posters and songs are living up to the hype.

The fans are in for a treat as Leo is slated to hit the screens on October 19.
