Both of director Nelson Dhilipkumar's movies Kolamaavu Kokila and Doctor had songs penned by Sivakarthikeyan. So it was no surprise when the actor was roped in for penning a song in Nelson's upcoming movie Beast, starring Vijay in the lead.

Beast is produced by Sun Pictures, and now it is being said that Etharkkum Thunindhavan (ET) from the same production house, has employed the services of 'lyricist' Sivakarthikeyan. ET is directed Pandiraj and has Imman's music and both of them have previously worked with the actor. 

Buzz is that Sivakarthikeyan was asked to write lyrics for a song in the Suriya starrer ET, owing to this good rapport. ET releases in theaters on February 4, 2022.
