Kumar, who also owns the music rights of Farah Khan's Tees Maar Khan, asked her husband Shirish Kunder to compose a track for the Salman Khan starrer.
Says a source from T-Series, "Farah's hubby has composed the theme song of TMK and Bhushan has been getting mind-blowing reactions from distributors and his friends. He too loved it. He asked Shirish recently at an event to compose a similar theme song for Ready."
The problem is, Pritam has already composed the music of Ready. "The composer will be very upset if Bhushan takes on another music director and hogs the credit. The composer will throw tantrum and refuse to compose any more songs so everything is very hush-hush now," notes the source.
Bhushan Kumar remained unavailable for comment.
