"I sing badly but I can sing just about anytime. I don't care about how I sing. I sing, I don't care," the 47-year-old said here Sunday in an interview.
"But to be suddenly put in a spot and being told to sing, then I get hesitant. If I am singing on my own then I am fine," Salman added.
As much as he is enjoying the curiosity created by 'Hangover' in Kick, Salman is also quite surprised to see the hype around him singing a song for a film.
"So all this hype is making me feel like I am singing for the first time. I have just sung a bit better than those two times," he added.
'Hangover' has been composed by Himesh Reshammiya.
Kick also stars Jacqueline Fernandez and hits theatres July 25.
