Refuting rumours that composer duo Vishal-Shekhar is upset with superstar Shah Rukh Khan, Rohit Shetty said this is not true.

The composers have scored music for Shetty-SRK's "Chennai Express", which also has a promotional song by Honey Singh.

`Vishal-Shekhar never had any problem with me or Shah Rukh. He was not there at the music launch because he had some prior commitments, ` Shetty told reporters during the promotion of the film here.

According to reports, Vishal and Shekhar were not happy with Honey Singh lending his voice for a song and and as a result, the composers stay away from the film's promotional activities.


`I really don't know what's his problem with Honey Singh and what he keeps tweeting about. We all had so much fun working together in 'Chennai Express', ` said Shetty.

Their displeasure was made obvious during the recent episode of `Indian Idol Junior` where SRK, Rohit and Deepika Padukone came to promote `Chennai Express`. Vishal-Shekhar, who judge the show with singer Shreya Ghoshal, were not present there.

Vishal keeps tweeting against Honey Singh on the microblogging site.

One of his tweet on Honey read: "It's hilarious and pathetic, how desperately this tacky rap-rapper is trying to ride on the fame of @iamsrk and 'Chennai Express'. Poor guy. "
